Asked by Emily

A carpenter has a piece of wood that is cut into two pieces. One piece of wood is 6
inches longer than the other. Four-fifths of the length of the longer piece of wood is 28
inches.

Which equation can be used to determine the length, x
, of the shorter piece of wood?

Answered by oobleck
write down what you know. Clearly, the two pieces have lengths
x and x+6

The longer piece is obviously x+6, so you also know that
4/5 (x+6) = 28
Now you can find x.
