Answer: x=4 *The answer should be the positive sign.*
Explanation:
distributive property: a(b+c)=ab+ac
division property of equality is dividing both sides of an equation by the same non-zero number does not change the equation.
a÷c=b÷c for c≠0
divide by 9 both sides of an equation.
x(2+7)/9=36/9
simplify.
36/9=4
9*4=36
36/4=9
4*9=36
x=4
Hope this helps!
