This is 24 because you have to set up TV and SU to each ssince they are equal. Then solve, so subtract 2x from 6x and then you have 4x. You divide 4 on both sides and x become 2, and last plug the x value into 6x
Is there answer options because if not then it would possibly be y = 45x + 540 or it could be 45x = 540 or it could be 45x/540 so it can be any of those :)
