Respuesta :
5(2x-8)=90
10x-40=90
add 40 to both sides
10x=130
divide 130 by 10
and the answer Is x=13
10x-40=90
add 40 to both sides
10x=130
divide 130 by 10
and the answer Is x=13
Answer: x=13
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!
