First you need to simplify the left side of the equation to get

Then you add by two on both sides to get

Finally you divide by 2 on both sides to get
Answer:
5k - 2
Step-by-step explanation:
To evaluate f(2 - k), substitute x = 2 - k into f(x), that is
f(2 - k) = 8 - 5(2 - k) = 8 - 10 + 5k = 5k - 2
The answers are:
a) 64x - 24
b) 19y
Your answer is 14 how i got it is simple first divide by 3 from 66 sense they multiply so it gonna be 22 NEXT minus 8 and your total/sum will be 14
Subtract 3/5b from both sides
8/5b+2=10
subtract 2 from both sides
8/5b=8
Divide both sides by 8/5
b=5
