Complete the steps to solve the equation. 9 – 4x = 2x 1. Addition property of equality: 9 = 6x 2. Division property of equality:

exis [7]

x = 3/2

Step-by-step explanation:

Given equation is:

$9 - 4x = 2x$

As we have to solve for x, x will be isolated on one side of the equation

So,

<u>1. Addition property of equality </u>

4x will be added on both sides

$9-4x+4x=2x+4x\\9 = 6x$

<u>2. Division property of Equality</u>

Dividing both sides by 6

$\frac{6x}{6}=\frac{9}{6}\\x = \frac{3}{2}$

Hence,

x = 3/2
