You would have to do distribution. So you would have to multiply 3 by 2a and multiply 3 by -8b. 3 times 2a equals 6a (always keep the letter) and 3 times -8b equals -24b. (if there is only one negative number when multiplying, always keep the negative sign.) now you are left with 6a-24b. and since we cant put a into b, your answer would be 6a-24b. hopefully this helped you and sorry if it confused you

Y can be found by setting the 3 angles in the bottom triangle equal to 180 degrees like so:
45 + 55 + y = 180
100 + y = 180 (Simplify)
y = 80 (Subtract 100 from both sides)
Angles x and y are opposite angles, so they are equal to each other. This means that x = 80 degrees also.
