### Example Question #2253 : Algebra 1

Solve for :

**Possible Answers:**

**Correct answer:**

can be simplified to become

Then, you can further simplify by adding 5 and to both sides to get .

Then, you can divide both sides by 5 to get .

### Example Question #2255 : Algebra 1

Solve for :

**Possible Answers:**

**Correct answer:**

To solve for , you must first combine the 's on the right side of the equation. This will give you .

Then, subtract and from both sides of the equation to get .

Finally, divide both sides by to get the solution .

### Example Question #1 : Linear Equations

Solve the following equation for :

**Possible Answers:**

**Correct answer:**

The first step is to distribute (multiply) the 2 through the parentheses:

Then isolate on the left side of the equation. Subtract the 10 from the left and right side.

Finally, to isolate , divide the left side by 2 so that the 2 cancels out. Then divide by 2 on the right side as well.

You can verify this answer by plugging the into the original equation.

### Example Question #3 : Solve Linear Equations With Rational Number Coefficients: Ccss.Math.Content.8.Ee.C.7b

Solve for :

**Possible Answers:**

**Correct answer:**

Combine like terms on the left side of the equation:

Use the distributive property to simplify the right side of the equation:

Next, move the 's to one side and the integers to the other side:

### Example Question #31 : Systems Of Equations

Solve for x:

**Possible Answers:**

**Correct answer:**

Simplify the parenthesis:

Combine the terms with x's:

Combine constants:

### Example Question #2 : Linear Equations

Solve the following equation when y is equal to four.

**Possible Answers:**

**Correct answer:**

Solve the following equation when y is equal to four.

To solve this equation, we need to plug in 4 for y and solve.

### Example Question #3 : Linear Equations

Solve the following:

**Possible Answers:**

**Correct answer:**

To solve, we must isolate x. In order to do that, we must first add 7 to both sides.

Next, we must divide both sides by 3.

### Example Question #4 : Linear Equations

Write an equation of the line passing through (5,10) and (10,2).

**Possible Answers:**

None of these.

**Correct answer:**

To find this line, first find the slope (m) between the two coordinate points. Then use the point-slope formula to find a line with that same slope passing through a particular point.

### Example Question #5 : Linear Equations

Solve for .

**Possible Answers:**

**Correct answer:**

First distribute out each side of the equation.

simplifies to .

Now for the right hand side,

becomes .

Now we equate both sides.

,

### Example Question #6 : Linear Equations

Solve for .

**Possible Answers:**

**Correct answer:**

First, we need to simplify what's inside the parentheses.

Now we continue to evaluate the left hand side.

The right hand side does not need any reduction.

We set the two sides equal to each other.
