First, open the parentheses (make sure you distribute the '-':
6x - 3x - 4 = x - 40
3x - 4 = x - 40
2x = -36
x = -18
The solution set is {-18}
Answer: f(x) = 9
Step-by-step explanation:
Plug in wherever you see x the value of f(5)
so you would do
4(5) - 11
20 - 11
Answer:
x=6 y=-3
Step-by-step explanation:
-3(f-5)=-9
-3f+15=-9
-15 -15
-3f=-24
Divided by -3
F=8
