Question

Solve the equation
`3 - x = - 9`

Answer 1

Answer: x = –12

Step-by-step explanation

Given

`3-x=-9`

To solve the equation, we have to isolate x.

• 1. Subtracting 3 from both sides of the equation

`3-3-x=-9-3`
`-x=-12`

2. Multiplying both sides of the equation times –1

`-x(-1)=-12(-1)`
`x=12`
