# Solving an Equation With Multiplication or Division

Solve the following equation $\frac{z}{8}$ = 9

### Solution

Step 1:

Given equation $\frac{z}{8}$ = 9 = $\frac{9}{1}$

To solve the equation, we isolate the variable by cross multiplying.

Step 2:

z × 1 = 9 × 8 = 72

So, z = 72

Solve the equation 7w = 56

### Solution

Step 1:

Given equation 7w = 56

To solve the equation, we isolate the variable by dividing both sides by 7.

Step 2:

$\frac{7w}{7}$ = $\frac{56}{7}$ = 8

So, w = 8
