You have to solve this algebraicly. To do this set up the proportion and add x to each term. You get 4x and 7x Set this equal to 33 4x+7x=33 Combine like terms and get 11x=33 Divide by 11 x=3 Now go back to 4x and 7x Multiply them by x and get 12(4×3=12) and 21(7×3=21) One group is 12 and the other is 21.
