Henry's current age is 10 times Justin's current age. In 6 years Henry's age will be 4 times Justin's age. Which system of equations can be used to calculate H, Henry's current age, and J, Justin's current age?
AJ = 10H
J +6=4(H+6)
BJ = H+6
J+4=H+10
CH = 10J
H+6=4(J+6)
D10J
H+4=6(J+4)
Please explain too!
