Is 3(x+4/3)-7=21 linear????

Algebra
1. Solve the equation below for x interms of a 4(ax+3)-3ax=25+3a 2. The formula for the sum of the degree measures of the interior angles of a polygon is S=180(n-2). Solve for n, the number of sides of the polygon, in terms of S. IM STRUGGLING PLEASE HELP

What are the tables for f (x) = |2x-1| f (x) = [[x]] + 3 f (x) = -|x-2| f (x) = |2 [[x-1]]| f (x) = [[x]]-2 f (x) = 2 [[x+1]]
