Question

Help me please justify each step 9x/4=-9 9x=-36 x=-4

Answer 1

$\dfrac{9x}{4}=-9\ \ \ |\text{Multiplication Property of Equality}\\\\4\cdot\dfrac{9x}{4}=4\cdot(-9)\\\\9x=-36\ \ \ \ |\text{Division Property of Equality}\\\\\dfrac{9x}{9}=\dfrac{-36}{9}\\\\x=-4$

Answer 2

Answer:

The justification is mentioned below.

Step-by-step explanation:

Given equation,

$\frac{9x}{4}=-9$

Multiply both sides by 4 ( multiplicative property of equality ),

$\frac{9x}{4}\times 4 = -9\times 4$

$9x=-36$

Divide both sides by 9 ( division property of equality )

$\frac{9x}{9}=\frac{-36}{9}$

$x=-4$
