The box below shows the first two of four steps for identifying equivalent expressions.• Simplify each expression. • Substitute a number for each variable. ••Which shows the last two steps in the directions?

After substituting a number for each variable, evaluate each expression using that number. Then compare the results: if the values are equal, the expressions pass this check as equivalent. This matches choice B, “Compute the value of each expression” and “Compare the values.”
