Question

What is the justification for step 4 in the solution process?

Answer 1

Answer:

Multiplication property of equality

Step-by-step explanation:

Given

Step 4: b = -27/8

Required

Which property justifies it?

First, it should be noted that step 4 is a result of step 3

When step 3 is multiplied by 3/8 on both sides, we have step 4;

i.e.

$\frac{8}{3b} = -9$

$\frac{8}{3b} * \frac{3}{8} = -9 * \frac{3}{8}$

$b = -9 * \frac{3}{8}$

$b = \frac{-9 * 3}{8}$

$b = \frac{-27}{8}$

The property that allows 3/8 be multiplied on both sides is referred to as the multiplication property of equality
