Question

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

Answer 1

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

Answer 2

The justification is mentioned below.

Explanation:

Given equation,

`(9x)/(4)=-9`

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

`(9x)/(4)* 4 = -9* 4`

`9x=-36`

Divide both sides by 9 ( division property of equality )

`(9x)/(9)=(-36)/(9)`

`x=-4`
