Question 5310
Let x = Rolex present age
Let y = Rose present age


(x-7) = 6(y-7)
x-7 = 6y - 42
x-6y = -35


(x+1) = 2(y+1)
x+1 = 2y+2
x-2y = 1


So, we have 2 equations:


x-6y = -35
x-2y = 1


Subtract these, to give -4y = -36 --> y = 9


x-2y = 1
x-2(9) = 1
x-18 = 1
x = 19


So present ages are: Rolex = 19 and Rose = 9
