wow this age problem is a mind twister huh
M=%282%2F3%29P
M-2=%281%2F2%29%28P%2B5%29
.
i hate fractions so i will change there appearance to whole numbers after substitution
M=%282%2F3%29P
%282%2F3%29P-2=%281%2F2%29%28P%2B5%29 multiply all by 6
4P-12=3%28P%2B5%29
4P-12=3P%2B15
highlight_green%28P=27%29
M=%282%2F3%29%2827%29
highlight_green%28M=18%29
