Steps for finding the solution

We have -1x + 86 = 101

First, we move the non x terms to the RHS of the equation. To do this, we subtract 86 from both sides.

Note: if a = b, then a - c = b - c

Therefore, -1x + 86 - 86 = 101 - 86

or, -1x = 15

Next, divide both sides by -1, which is the coefficent of x

Note: if a = b, then a ÷ c = b ÷ c

-1x/-1 = 15/-1

x = 15/-1 or, x = -15
