and found the solution (2, 5). To show that this is actually a solution, substitute x = 2,y = 5 into each of the equations and see if the resulting left sides and right sides are equal. So for the first equation
when x = 2 and y = 5
Thus the (2, 5) is a solution to the first equation. Now the second equation
when x = 2 and y = 5
Thus the (2, 5) is a solution to the second equation also. Now try your problem,
