highlight_green%28%28n%2B%28n%2B17%29%294=77%2Bn%29. The translation into symbols for the description.

n is the number.
Solve the equation for n.

%282n%2B17%294=77%2Bn
8n%2B68=77%2Bn
7n%2B68=77
7n=9
highlight%28n=9%2F7%29

Let number be N

Then: 4(N + 17) = N + 77

4N + 68 = N + 77

4N - N = 77 - 68

3N = 9

N, or number = 9%2F3, or highlight_green%28highlight_green%283%29%29
