Answer: x=-8 and -8=x. *The answer should have negative sign.*

Explanation:

distributive property: a(b+c)=ab+ac

subtraction property of equality is subtracting the same number from both sides of an equation does not change the equation.

subtract 4 both sides of an equation.

-12x+4-4=100-4

simplify.

-12x=96

divide by -12 both sides of an equation.

-12x/-12=96/-12

96/12=8

96/8=12

8*12=96

12*8=96

It change positive to negative sign.

x=-8

Hope this helps!

Thanks!

Have a great day!
