Question

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

Answer 1

25x + (-11) = -86        

25x - 11 = -86             | + 11

25x - 11 + 11 = -86 + 11

25x = -75             | ÷ 25

25x ÷ 25 = -75 ÷ 25

x = -3

Answer 2

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
