Question

8(2x+5)=2(3x+5) comprobacion

Answer 1

8(2x+5)=2(3x+5)
16x+40=6x+10
10x=-30
X=-3
Comprobación
8(2*-3+5)=2(3*-3+5)
8(-6+5)=2(-9+5)
8*-1=2*-4
-8=-8

Answer 2

Respuesta:

8(2x+5) = 2(3x+5)

16x + 40 = 6x + 10

16x - 6x = 10 - 40

10x = -30

x = -3

Comprobamos:

8(2(-3)+5) = 2(3(-3)+5)

8(- 1) = 2(- 4)

- 8 = - 8
