3 times 6.5 is 19.5
=19.5+x-xTIMES 9y
I'm sorry if these aren't 100% correct but I just did it how I learned but I sort of forgot and that's how I remember...
8.
2 times 8.7 is 17.4
2 times 1.5 is 3
17.4+3 is 20.4
20.4+3 is 23.4
8.7+1.5 is 10.2
10.2 times 23.4 is 33.6
1.5 times 1.5 is 2.25
33.6-2.25 = 31.35
