6.2A Solving Systems by Substitution (isolated)
Solve each system by substitution.
Steps 1) Solve one of the equations for x or y.
? This is already done for you for this section.
2) Substitute the expression into the other equation and solve for the variable.
3) Once you solved one for one of the variables, plug this solution into one of the original equations and solve for the other variable.
4) Check your answer by plugging it back into both equations and seeing if it holds true.
