resposta:

5 -5x -2x+1 = -6 -3x

5 -5x -2x+1 = -6 -3x5 + 1 -5x-2x = -3x -6

5 -5x -2x+1 = -6 -3x5 + 1 -5x-2x = -3x -66 -7x = -3x -6

5 -5x -2x+1 = -6 -3x5 + 1 -5x-2x = -3x -66 -7x = -3x -6-7x +3x = -6 -6

5 -5x -2x+1 = -6 -3x5 + 1 -5x-2x = -3x -66 -7x = -3x -6-7x +3x = -6 -6-4x = -12

5 -5x -2x+1 = -6 -3x5 + 1 -5x-2x = -3x -66 -7x = -3x -6-7x +3x = -6 -6-4x = -12x=-12/-4

x = 3
