sorry, I thought you get it so I left for others. after getting s and t, you replace to one of the original [x,y] to get values of x and y . conclude that [x,y] = [ number you get, number you get] . that's it

I got s =46, now replace [x,y] = [12,7] + 46[8, 5] = [356, 237] I think so, if it's not the answer, I am sorry, I cannot help
