5(2x-8)=90
10x-40=90

<u><em>Answer: x=13</em></u>

Step-by-step explanation:

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

addition property of equality is adding the same number to both sides of an equation does not change the equation.

divide by 5 both sides of an equation.

5(2x-8)/5=90/5

simplify.

2x-8-18

add 8 both sides of an equation.

2z-8+8=18+8

simplify.

2x=26

divide by 2 both sides of an equation.

2x/2=26/2

simplify.

26/2=13

13*2=26

2*13=26

x=13

Hope this helps!

Thanks!

Have a great day!
