Solve this showing work. worth 50 points
goldfiish [28.3K]

Answer:

10. X=3

11. FG=15

12. QS=34

Hope this helps

Step-by-step explanation:

10. 8x+11=12x-1

8x-12x=-1-11

11x-7=-9+7

8x=16

x=2

Substitute the (x)

11(2)-7 =15

12. 5x-3=21-x

5x+x=21+3

6x=24

x=4

Substitute the (x)a

5(4)-3=17

21-(4)=17

17+17=34
