The product is the answer of a multiplication problem so its 9×10 which equals 90
Expand the brackets on the right side so,,
12x + 20 = 6x + 24
Collect like terms and place the x’s on one side and the numbers on one side ,,
6x = 4
Divide both sides by six to get x alone,,
X= 6/4
X = 1.5

There are infinitely many solutions because the first two equations are actually the same just arranged differently so there's not enough information to know what x or y are in other words they could be anything.
