2(c-3)=s
because you have to subtract 3 years from sherman's age first, so you need the parentheses
<span>-18, -13, -8, -3,…
-18 + 5 = -13
-13 + 5 = -8
-8 + 5 = -3
-3 + 5 = 2
2 + 5 = 7
7 + 5 = 12
Therefore, the next three terms are 2, 7, 12

X=number of females
47-x=number of males
# of males is 2*(number of females)-7:
47-x= 2x-7
add x to both sides:
47=3x-7
add 7 to both sides:
54=3x
divide both sides by 3:
x= 18 females
47-18= 29 males
4x + 2 < 14
4x < 14 - 2
4x < 12
x < 12/4
x < 3
S = { x <3 }
