I thought, S = 150  J < sub 2J + 3.5(150  J) = 405 2J + 525  3.5J = 405 1.5J = 120 J = 80, is that right?

@hartnn , got a question. If I had, 2x + y = 3, and I wanted to put in y = mx + b I would say: y = 2x + 3, or would the 2x be negative because I switched it's side?

a better way to explain that is 2x+y=3 subtracting 2x from both sides 2x2x+y= 2x +3 i subtracted because we need to do inverse operation, since 2x was added to y, to isolate y, you subtract it.
