Question

resolver 3.(2x+2)+4 = -2(2x-6)-2 ​

Answer 1

Respuesta:

3(2x+2)+4 = -2(2x-6)-2

3(2(x+1))+4 = -2(2(x-3))-2

(3(2))(x+1)+4 = (-2(2))(x-3)-2

6(x+1)-4 = -4(x-3)-2

6x+6-4 = -4x-(-12)-2

6x+(6-4) = -4x+12-2

6x+2 = -4x+(12-2)

6x+2 = -4x+10

6x+2+4x = -4x+10+4x

(6+4)x+2 = (-4+4)x+10

10x+2 = 10

10x+2-2 = 10-2

10x = 8

10x/2 = 8/2

5x = 4

5x/5 = 4/5

x = 4/5
