Question

resolva a equação.
5(1-x)-2x+1=-3(2+x)

Answer 1

5(1-x)-2x+1=-3(2+x)
5 -5x -2x+1 = -6 -3x
5 + 1 -5x-2x = -3x -6
6 -7x = -3x -6
-7x +3x = -6 -6
-4x = -12
x=-12/-4
x = 3

Answer 2

5.(1 - x) - 2x + 1 = - 3.(2 + x)
5 - 5x - 2x + 1 = - 6 - 3x
5 + 1 - 5x - 2x = - 6 - 3x
6 - 7x = - 6 - 3x
6 + 6 = - 3x + 7x
12 = 4x
4x = 12
x = 12/4
x = 3
