Solve for x. 3x + 4^2 + x - 10 = 14
First step: simplify the equation. Combine the x's, 3x + x = 4x, Then solve 4^2 = 16 So, 4x + 16 - 10 = 14 Second: Subtract 16 from 10 = 6 So, 4x + 6 = 14 Third: Get x by itself on one side. Subtract 6 from both sides So, 4x = 8 Fourth and final step: you have to get x by itself Divide 4 from each side So, x = 4
