Answer: x=-8 and -8=x. *The answer should have negative sign.*
Step-by-step 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!
