gabriel is 3 years younger than frank. when their ages are doubled frank is 6 years older than gabriel. finally the current total of their ages right now is 17.which of the following could be gabriel's age right now?

Answer 1

G = F - 3

G + F = 17

Substitute F-3 for G in the second equation and solve for F. Insert that value into the first equation to solve for G. Check by putting both values into the second equation.

Answer 2

Frank is X years old.
Gabriel is x-3 years old.

When their ages are doubled:
Frank is 2x years old.
Gabriel is 2x-6 years old.

x + (x-3) = 17.
2x-3 = 17
X = 10 years = Frank's age.
x-3 = 10-3 = 7 years = Gabriel's age.

Answer 3
