Answer:
Step-by-step explanation:
13.
6 =x − 24
Collecting like terms
6 + 24 = x
x = 30
14.
10 +w/3 = 2
Multiply each term by 3
30 + w = 6
Collecting like terms
w = 6 - 30
w = -24
15.
13 = −11 − 4x
Collecting like terms
4x = -11 - 13
4x = -24
Dividing by 4
4x/4 = -24/4
x = -6
Answer:
f(5)=38
Step-by-step explanation:
f(5) means x=5, or in this case, a=5. We plug in 5 as A. f(5)=7(5+1)-4. f(5)=7(6)-4.
f(5)=42-4
f(5)=38
Answer: 
Step-by-step explanation:
For this exercise it is important to remember the following:
