Use any method. If there is not a unique solution to the system, state a reason.6x −y =30(1)7x + 4y =66(2)We can use any method to solve this system. Notice that we can eliminate the variable y by multiplying the first equation by so, let's use the addition method.4,Multiply each side of equation (1) by and simplify.44(6x) − (4)(y) = 4(30)24x − 4y = 120(3)Now add equations (2) and (3).24x −4y =120(3)7x +4y =66(2)_____________31x=186Add (3) and (2).The resulting equation contains just the variable x; the variable y has been eliminated. Solve the above equation for x.
