Isolate the variable by dividing each side by factors that don't contain the variable.
B=7
3(b-4)+5b=44
3b-12+5b=44
8b=44+12
8b=56
b=7

Quesiton 7:
To find perimeter we add all the sides together.
x+2x+2x+5=145
Combine all the x's.
5x+5=145
To isolate the constants, subtract 5 from both sides.
5x=140
Now divide both sides by 5 to isolate the x.
x=28
The questions asks for the length of AC, so to find that we need to insert our new x.
AC= 2(28)+5
56+5=61
