Question

7(x-1-2)-2(x-5)=x-5 me ajuda

Answer 1

Aplicar a distributiva

7. (x - 1 - 2) -2(x - 5) = x -5
7x - 7 - 14 - 2x + 10 = x - 5
7x - 2x - 21 + 10  = x - 5

5x - 11 = x - 5
5x - x = - 5 + 11
4x  = 6
x = 6 / 4   (÷2)
x = 3/2

Resposta: x = 3/2

Answer 2

7x -7 -14 -2x + 10 = x - 5
7x -2x -x = -5 +7 +14 -10
4x = 6
x = 6/4
x = 1.5
