Start at -150, then add 3(-5), then add 122.2. -150 + 3(-5) + 122.2 = -45.3
8x-5y because 7x plus x is 8x and -6y+y is 5y
5(x + 3) - 3(x - 2) = 19 That should give you the result you need. The answer will come out to be x = - 1
If you want it to be - 1 to start with, then
2(5x + 3) - 13x + 2 = - 1
X time 0.8 (or 80 percent)= 15
so 15/0.8=X
18.75
B if you need an explanation just comment
