15. 
Add "g" on both sides
Multiply 5 on both sides to get x by itself
x = 5(a + g)
x = 5a + 5g
18. a = 3n + 1
Subtract 1 on both sides
a - 1 = 3n
Divide 3 on both sides to get n by itself
= n
21. M = T - R
Add "R" on both sides to get "T" by itself
M + R = T
24. 5p + 9c = p
Subtract "5p" on both sides
9c = p - 5p
9c = -4p
Divide 9 on both sides to get "c" by itself
c = 
or c = 
27. 4y + 3x = 5
Subtract "4y" on both sides
3x = 5 - 4y
Divide 3 on both sides to get "x" by itself
x = 
x =

Answer:
30
Step-by-step explanation:
x = 4
=> 4x + 14
=> 4(4) + 14
=> 16 + 14
=> 30
Answer:
Two more people.
Step-by-step explanation:
If 4 people can mow a lawn in 6 hours, then 4 people can mow 1/6 of a lawn in 1 hour.
If 4 people can mow 1/6 of a lawn in 1 hour, then 1 person can mow 1/24 of a lawn in 1 hour.
If 1 person can mow 1/24 of a lawn in 1 hour, then 6 people can mow 1/4 of a lawn in 1 hour.
If 6 people can mow 1/4 of a lawn in 1 hour, then 6 people can mow a lawn in 4 hours.
6 people minus 4 people is 2 people.
