Answer:
37
Step-by-step explanation:
3x + 8x + 4x = 6x + 63 ( combine like terms)
>15x = 6x + 63 (subtract from both sides)
-6x. -6x
-----------------
>9x = 63. (divide both sides by 9)
--------------
9. 9
> x = 7 ( use this to plug in for your new equation)!
5(x) + 2
>5(7) + 2 (multiply 5*7)
> 35 +2 (then add)
> 37 is your answer
