You’re solving for x, and you need to isolate x so it equals one number on the other side. Multiply by both sides by 14. 4x - 1x = -3, which reduces to 3x = -3, so x = -1. For 5, multiply both sides by 4. -3x + 1 = 2 which reduces to -3x = 1, so x = -1/3. For 6, multiply both sides by 4. x + 8 = 3. So x = -5. Make sure to check by plugging in x for each problem.
