By dividing each general term by 3.
Example:
(3/3=1)
<span>3(x + 5) = 2(3x + 18)
Use the distributive property:
3(x)+5(3)=2(3x)+18(2)
Simplify:
3x+15=6x+36
6x+36=3x+15
3x+36=15
3x=-21
x=-7
Check answer:
3(-7+5)=2(-21+18)
3(-2)=2(-3)
-6=-6
Hope this helps :)

Answer: 2
plug in 5 for x in the f(x) equation and get 14, plug -1 for x in the g(x) equation and get 7. 14/7=2
