Ok so 1. is 4X-1 and 2. is well i can't see that but 3. is X+5 and can't see 4 but 5. is 30-20X can't see 6. but 7. is well im just gonna have to work this out its to much to do in my head. 12-2X + 5X+ 10 but we aint done yet. the answer for 7. is 3X + 22 and then I can't see 8 or 10 but 9 is oh im gonna work this out to 4X + 6 -4X +8 (negative plus negative equals positive) so the you get 14 as your answer for number 9 bc the X's get canceled out. Hope this helps if not lmk
