Answer:
D
Step-by-step explanation:
4x - 2(x + 3) = 8
Use distributive property
4x -2x - 6 = 8
2x - 6 = 8
2x = 8 + 6
2x = 14
x = 14 ÷ 2
x = 7
-4r-11=4r+21
Move 4r to the other side
Sign changes from +4r to -4r
-4r-4r-11=4r-4r+21
-4r-4r-11=21
-8r-11=21
Move -11 to the other side
Sign changes from -11 to +11
-8r-11+11=21+11
-8r=21+11
-8r=32
Divide both sides by -8
-8r/-8=32/-8
