xy = x times y times the number behind it, with that info...
For this problem to be solvable, we have to have values for x and y. Lets say x is 6 and y is 7.
[tex]6 * 7 = 42\\\\42 * 2 = 84\\\\5 * 5 * 6 = 150\\\\84 + 150 = 234\\\\234 * 7 = 1,638\\\\6 * 7 * 7 = 294\\\\1638 - 294 = 1,344[/tex]
Your answer should be 1,344. Answer may vary with x and y.
