ok, you were given 2 equations, 1st is 8x + 5x + 2x + 4x = 114, 2nd is 5x + 3 = ?.
You have to find x in the 1st equation in order to solve the 2nd equation.
So let's find x first...
8x + 5x + 2x + 4x = 114
19x = 114
x = 6
Now that you know x, you could solve the 2nd equation...
5x + 3 = ? now since you now know x=6
5 (6) + 3 = ...
Just calculate the answer.
Hope this helps!

8x + 5x + 2x + 4x = 114
Always combine like terms. Here, the like terms are 8x,5x,2x,4x. After combining like terms, this is how the equation will look like:
19x=114
divide 19
x=6
Plug in x to the other equation.
5(6)+3=30+3=33

19x = 114
x = 114/19
x = 6
5x + 3 =
5(6) + 3 =
30 + 3 = 33

Combine like terms, the x.
19x=114
divide each side by 19
when u get your answer, plug the x in the other equation
5x+3=
and you have your answer!
