### Example Question #71 : Solving For The Variable

Solve for .

**Possible Answers:**

**Correct answer:**

Start by adding to both sides.

Next, square both sides to get rid of the square root.

Finally, subtract from both sides.

### Example Question #71 : Solving For The Variable

Solve for :

**Possible Answers:**

None of these answers

**Correct answer:**

To solve for , all you have to do is simplify your equation until you get a number on one side and your on the other.

So for starters we already have all of our numbers on one side: . Now all we need to do is add and subtract when called for in order to get our answer.

Start by adding to

Now subtract from our newly formed

Your answer is

### Example Question #123 : Algebra

Solve for :

**Possible Answers:**

None of the other answers

**Correct answer:**

In order to solve for , all you have to do is simplify your equation so that your is on one side and your number is on the other.

For this equation, we have one number accompanying our . That is : .

Let's move that over to the other side by adding it on both sides.

Now that all of our numbers are on one side, it's time to simplify. Multiplication comes before addition, so we need to multiply the and together before we touch the .

Now we can add the to .

Our answer is

### Example Question #124 : Algebra

Solve for :

**Possible Answers:**

None of the other answers

**Correct answer:**

In order to solve for , we must simplify our equation so that we have on one side and our final number on the other side.

Before we can do any simplifying, we must get by itself. Currently our is being added by , but it's also being divided by . We can't touch the yet, so let's move the by multiplying both sides.

Now let's move that on the side by subtracting it on both sides.

Now that we have all our numbers to one side, it's time to start simplifying. Multiplication comes before subtraction, so we're going to multiply our and together.

Now we can subtract our from .

Our answer is

### Example Question #71 : Solving For The Variable

Evaluate .

**Possible Answers:**

**Correct answer:**

Solve this equation for by isolating the on the left side of the equation. This can be done by first, subtracting from both sides:

Collect like terms by subtracting coefficients of :

Add 17 to both sides:

Divide both sides by 3:

,

the correct choice.

### Example Question #71 : Solving For The Variable

Evaluate .

**Possible Answers:**

### Example Question #72 : Solving For The Variable

Rearrange the following equation so that it is solved for "b"

**Possible Answers:**

**Correct answer:**

Rearrange the following equation so that it is solved for "b"

This problem may look intimidating, but don't be overwhelmed! Read the problem carefully, all we need to do is get the b all by itself.

To do this, let's first multiply both sides by 4x.

Next, we simply need to divide both sides by 3 to get the b all by itself.

One last thing, we can simplify the denominator and get rid of our three by dividing a three out of the 12 and the 6.

This yields:

### Example Question #71 : Solving For The Variable

Solve for x

**Possible Answers:**

**Correct answer:**

Starting with

We must get rid of the fraction by multiplying both sides by (2x-1)

The terms cancel on the right, and we must distribute on the left

Simplify

Subtract x from both sides to get the variables all on one side

combine like terms

Now add 3 to both sides to get the term with the variable by itself

Simplify

And finally, divide both side by 5 to get the variable all by itself
