Subtract.

11X- (9+7x) =?
(Simplify your answer.)

The answer would be 4x-9
steps :
11- 9-7x
11-7x
4x-9

I'll do the first one for you. it isn't very hard at all.on number one, you have (50 × 3), which equals 150, and (3 × 3), which equals 9. after you establish that, you add 150 and 9 together. so, (150 + 9) equals 159.this means that 53 × 3 = 159.

The graph isn’t that clear
