Question

Which expression is equivalent to 2 3 (3x + 9y) + 1 2 (4x - 2y)?

Answer 1

assuming that you are talking about 2 times 4 and 1 times 2 which i am confused about because of the space in between the answer would be 18x +54y +8x-4y which simplifies into 26x+50y

Answer 2

4x+5y

Explanation:

Next time, add a / or something to let us know that 2/3 and 1/2 are fractions.

The way i had done this is multiplying 3x+9y by 2, which becomes 6x+18y, then dividing it by 3, which becomes 2x+6y

Then, divided 4x-2y by 2, since anything times 1 is itself. This would result in 2x-y.

Finally, You simply just add the (2x+6y) + (2x-y), which results in 4x-5y.
