To solve this system of equations we must make the coefficients of y equal in values and different in signs, then multiply equation (1) by -5

Add equations (2), (3) to eliminate y

Now divide both sides by 17 to find x

Substitute the value of x in equation (1) to find the value of y

Add 10 to both sides

Divide both sides by 2 to find the value of y

The solution of the system of equation is (5, -6)
