Question

Justify each step of the equation solved below using mathematical properties.

1. -3(x+2)+4=94
2. -3x-2=94
3. -3x-2=94
4. -3x=96
5. X=-32

Answer 1

Please check the explanation!

Explanation:

1. -3(x+2)+4=94

Apply distributive law a(b+c)=ab+ac and combine like terms for the second and third steps

2. -3x-2=94

3. -3x-2=94

Add 2 to both sides.

4. -3x=96

Divide both sides by -3.

5. X=-32
