If 3x years from today Hallie will be 3y+4 times her present age what is Hallie's present age in terms of x and y?

Question

anonymous · Answer

If you let P be her present age, then you can set up an equality.  In 3x years, she will be P + 3x.  At that time, she will also be (3y+4)P.  You can set these equal to each other and solve for P in terms of x and y.

Im stuck on how to solve 3x=3py+4p

anonymous · Answer

On the right hand side, factor out a "p" from each term.

anonymous · Answer

i meant 3x=3py+3p

anonymous · Answer

3x=3py+3p is the correct equation to work with.  And now I repeat to you: On the right hand side, factor out a "p" from each term.

To factor ab + ac, you get a(b+c).  Do the same for the right-hand side.
