i just looked at the chart. the dots for G and H are connected to little lines at the bottom of the graph and to the side. find out the numbers and write it like your supposed to write it.
So assuming that the total =27 r+b=27 r=-5+3b r=3b-5 subsitute 3b-5 for r in first equation 3b-5+b=27 4b-5=27 add 5 4b=32 divide by 4 b=8 subsitute b+r=27 8+r=27 subtracct 8 r=19
