the ratio they give you suggest a fraction\[\frac{ab}{cb}=\frac13\]rewriting this we get:\[3ab=cb\] input the values of ab and cb that are in the problem 3x = 2x+3 and solve for x

once you know x, you can then determine the specific values for ab and cb

this is as basic as algebra gets ... 3x = 2x+3 what are some ideas you have that might be useful in solving it?

:) lets start by getting the xs to one side .... id suggest subtract 2x from each side 3x = 2x+3 -2x -2x ------------ what do we get here?

1x=3???
amistre64
  • amistre64
correct so, since x = 3 and cb = 2x+3 or cb = 3x what is the value of cb?
