Best ResponseYou've already chosen the best response.0\[Molly + 4 = Heidi\] \[2*(Molly + 3) = Heidi + 3\] Can you solve it on your own?

Best ResponseYou've already chosen the best response.0you know from the first statement/equation, that Heidi = Molly + 4 . I you substitute this into the second Equation it looks like this: \[2 * (Molly + 3) = (Molly + 4) + 3\] So now you can solve for Molly and plug it back into either the first or the second equation...

Best ResponseYou've already chosen the best response.1I don't think so, because it was said that Molly is 4 years younger than Heidi, and 116=5 should be 4!!

Best ResponseYou've already chosen the best response.1You got Heidi's age correct. Review your work and see if you made an arithmetical error.

Best ResponseYou've already chosen the best response.1Actually you did not get heidi's age right. They are both wrong.

Best ResponseYou've already chosen the best response.1Do this one over and see what you get. 2 * (Molly + 3)= (Molly +4)+3 What did you get for Molly?

Best ResponseYou've already chosen the best response.1Let M= Mollly, so that it will look like this: 2(M+3)=(M+4)+3

Best ResponseYou've already chosen the best response.1Lets see where you are going with this. starting with the eequation 2(M+3)=(M+4)+3 Remove paren' 2M+6=M+4+3 consolidating like terms 2M+6=M+7 do we agree thus far?

Best ResponseYou've already chosen the best response.1Next step is to subtract 1M and 6 from both sides of the equal sign. 2MM+66=MM+76 Consolidating similar terms Now you have Molly's age!

Best ResponseYou've already chosen the best response.1What did you get when you combined the terms of the equation?
