2-74b Build the equation 2x – 5 = –1 + 5x + 2 using your tiles by placing 2x – 5 on the left side and
–1 + 5x + 2 on the right side. Then use your simplification skills to simplify this equation as much as possible so that x is alone on one side of the equation. Use the fact that both sides are equal to solve for x. Record your work.
