2( x-1) - 3 ( -1 -x) + 5 ( x - 2) =-x

Answer 1

Explicação passo-a-passo:

2( x-1) - 3 ( -1 -x) + 5 ( x - 2) =-x

2x - 2 + 3 + 3x + 5x - 10 = - x

2x + 3x + 5x + x = 2 - 3 + 10

11x = - 1 + 10 ---> 9

x = 9/11

Answer 2

Explicação passo-a-passo:

2 (x-1) -3 (-1-×) + 5 (×-2) = -×

2 × - 2 + 3 + 3 × + 5 × -10 = - ×

2 × + 3 × + 5 × + = 2 - 3 + 10

11 × = - 1 + 10 --> 9

x = 9/11
