Let x = Brice's age and y = Brittany's
x = y - 15
2(x-3) = y-3
Substitute y-15 for x in the second equation and solve for y. Then put that value in the first equation to solve for x.
x = y - 15
2(x-3) = y-3
Substitute y-15 for x in the second equation and solve for y. Then put that value in the first equation to solve for x.
