Question

7.(x-1)-4.(1+2x)=x-11 por favor me ajudem

Answer 1

7.(x-1)-4.(1+2x)=x-11

7x - 7 - 4 - 8x = x - 11
7x - 8x - x = - 11 + 7 + 4
- x - x = - 4 + 4
- 2x = 0(-1)
2x = 0
x = 0/2
x = 0

Answer 2

7.(x-1)-4.(1+2x)=x-11

7x-7-4-8x=x-11

7x-8x-x=-11+8+4

-x-x=-3+4

-2x=1

x=- 1/2

espero ter ajudado!

boa tarde!
