In these types of problems, the first step is to combine like terms. Like terms are terms with the same exponent (power), and the same variable (like all x's). In the above equation, we can combine -5x, 2x and -3y. Let's do it:

The next step would be to factor out the common ratio, which is not applicable here, so your answer would be
-6x + 7y. Hope this helps!
Oh. I thought you meant 3-6, not questions 3 through 6. Sorry :(
Answer:
The answer to your question is: the height of the light pole is 15 ft.
Step-by-step explanation:
See the picture below
Now, we can do proportions to finds the height of the light pole

Solve for x
x = 6(20) / 8
x = 120 / 8
x = 15 ft
N, N+2, and N + 4 are the ages
(N + 4) - (2N) = (N + 2) -24
4 - N = N - 22
2N = 26
N = 13
The brothers are 13, 15, and 17 years old.
