learning the math is really secondary, per se
math is the tool to teach you how to reason and logically solve problems
A + B + C = 180º
B = 3A
C = 2A + B
substituting ___ C = 2A + (3A) = 5A
substituting ___ A + (3A) + (5A) = 180º ___ 9A = 180º ___ A = 20º
substituting ___ B = 3(20º) = 60º
substituting ___ C = 5(20º) = 100º
