5x + 10 = - 4x - 17 what is x

5x + 10 = - 4x - 17

+4x + 4x

5x + 4x = 9x

9x + 10 = - 17

-10 - 10

-27

9x = - 27 9x/9 = - 27/9

x = - 3

this is how you solve for x;

5x + 10 = - 4x - 17

5x + 4x + 10 = - 4x + 4x - 17 (add 4x on both sides)

9x + 10 = - 17

9x + 10-10 = - 17 - 10 (subtract 10 on both sides)

9x = - 27 (next do the inverse operation of x)

x = - 27 : 9

x = - 3
