Can someone i’m kinda stuck on these two questions can someone answer for me

What are the steps to solving the inequality 3b + 8 ≥ 14?

The tuition costs, c, for a local community college are modeled by c(h) = 250 + 200h, where h represents the number of credit hours taken. the local state university has tuition costs, s, modeled by the function s(h) = 300 + 180h. how many credit hours will a student have to take for the two tuition costs to be equal? round the answer to the nearest tenth of an hour.

What does x = in this equation x+3+2x=x+5
