The second equation is already in standard form. Put the first one in standard form also:





Multiply the first equation by 4 and the second one by 5:





Add like terms:



Solve for





Substitute this value for in either of the original equations and then solve for







The solution set is:



Verify:





and





The ordered pair we claimed as the solution set satisfies both equations.
