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

-4x=-12

x=3

11. 11x-7=3x+9

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

Step-by-step explanation:

<u>Step 1: Define</u>

R(x) = 6x - 3

S(x) = -3x - 8

<u>Step 2: Find</u>

  1. Substitute in functions:                                                                                     R(x) - S(x) = 6x - 3 - (-3x - 8)
  2. [Distributive Property] Distribute negative:                                                    R(x) - S(x) = 6x - 3 + 3x + 8
  3. [Addition] Combine like terms:                                                                        R(x) - S(x) = 9x + 5
