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.
