# Solving linear equations using multiplication and division

### Solving linear equations using multiplication and division

In the previous lessons, we have learned what a linear relationship is and its graphs and tables. In this lesson here, we will then learn how to solve one-step linear equations by multiplication and division.

#### Lessons

• 1.
Solve the following equations.
a)
$- \frac{9}{7} = 3x$

b)
$\frac{x}{3} = \frac{5}{7}$

c)
$3\frac{1}{4} = 1\frac{1}{2}x$

d)
$- \frac{6}{5}x = - \frac{9}{8}$

• 2.
Solve.
a)
$- 0.25 = \frac{x}{{ - 1.2}}$

b)
$6.3 = - 4.7x$

c)
$\frac{{2.2}}{x} = - 6.6$

d)
$4.5x = 8.1$

• 3.
A laptop is on sale at 35% off. The sale price is \$342.99 less than the original price. What is the sale price of the laptop?
