32 - 6x + 7x = -15 + 28

32 - 6x + 7x = -15 + 28 equals x = -19.

First, simplify 32 - 6x + 7x to 32 + x. / Your problem should look like: 32 + x = -15 + 28.
Second, simplify -15 + 28 to 13. / Your problem should look like: 32 + x = 13.
Third, subtract 32 from both sides. / Your problem should look like: x = 13 - 32.
Fourth, simplify 13 - 32 to -19. / Your problem should look like: x = -19, which is your answer.
