Solving One-Step Equations: Multiplication and Division

It's still easy to solve
linear equations
when only multiplication or division is involved. If there's a coefficient in front of the variable, multiply by the
reciprocal
of that number to get a coefficient of 1.

**
Example 1:
**

Solve.

The
inverse operation
of multiplication is division. So, divide both sides by 3.

**
Example 2:
**

Solve.

**
**

The inverse operation of division is multiplication. So, multiply both sides by 7.
