Read each step of the Substitution method for solving a System of Equations. Then, match the result of performing the step with the step.

• y = 5 - 2x

• Step 2: Substitute the expression in the other equation

• -3x + 6(5-2x) = 0

• Step 1: Solve one equation's variable (expression)

• (2, 1)

• Step 3: Solve the equation for a value

• x = 2

• Step 5: Present the solution as an ordered pair

• 2(2) + y = 5

  y = 1

• Step 4: Substitute the variable's value in the other equation; solve
