Add the additive inverse of the term to both sides.



Multiply both sides by the reciprocal of the coefficient on



Substitute the value 3 for and the value -2 for and do the indicated arithmetic:





Checks. The ordered pair is in fact an element of the solution set of the equation .

Do the other one the same way.
