5b+9m=150.5

9b+5m=175.7 if you add them you have one equation.

14b+14m=326.2

14(b+m)=326.2

b+m=23.3

b=23.3-m

sub. this back into one the original equations

9(23.3-m)+5m=175.5

209.7-9m+5m=175.5

-4m=-34.2

m=8.55

Plug that into the other equation

5b+9(8.55)=150.5

5b+76.95=150.5

5b=73.55

b=14.71
