What is x in the equation 25x + - 11 = - 86

25x + (-11) = - 86

25x - 11 = - 86 | + 11

25x - 11 + 11 = - 86 + 11

25x = - 75 | : 25

25x : 25 = - 75 : 25

x = - 3

25x + - 11 = - 86

Add 11 to both sides, so to - 11, it cancels out, as well as - 86, which leaves you with 25x = - 75

Then divide by 25 on both sides, 25x becomes just x, and - 75 becomes - 3.

Therefore x = - 3
