p, plant flowers
b, baby sit
c, clean house

system%28p%2Bb%2Bc=20%2Cb=3c%2Cp=b-1%29


Rewrite the first equation all in terms of b.
%28b-1%29%2Bb%2Bb%2F3=20

b-1%2Bb%2Bb%2F3=20
2b%2Bb%2F3=21
6b%2Bb=63
7b=63
highlight%28b=9%29------hours baby sitting

highlight%288%29------plant flowers

highlight%283%29------cleaning house
