Asked by JOHN

6 YEARS AGO, JOE WAS 2 YEARS MORE THAN 5 TIMES AS OLD AS HIS DAUGHTER. SIX YEAS FROM NOW, HE WILL BE 11 YEARS MORE THAN TWICE AS OLD AS SHE WILL BE. HOW OLD IS JOE?
Answered by scott
J - 6 = 5 (D - 6) + 2 ... J - 6 = 5 D - 28

J + 6 = 2(D + 6) + 11 ... J + 6 = 2 D + 23

5 D - 22 = 2 D + 17

solve for D , substitute back to find J
