-5 = -8 -x First, we need to get x isolated (put on one side of the equation by itself), and then divide by -1 to get rid of the negative sign. Add 8 to both sides. -5 + 8 = 3 -8 + 8 = 0 You are left with: -x = 3 Now, we must divide both sides by -1 to solve for x. -x / -1 = x 3 / -1 = -3 You are now left with the following solution: x = -3
