Answer:
−4+5−2
Step-by-step explanation:
Just combine the like terms which are 3y and 2y, you add and get 5y and everything else stays the same
Combine like terms to get 2x + 6x which is 8x and 3y + 9y which is 12y so the simplified answer is 8x + 12y
The answer is 2 cause you have to do the asides individually
33 photos in a 4x to 7x ratio
4x + 7x = 33
11x = 33
x = 3
33 photos can be put in a 4(3) to 7(3) ratio
which is a 12 to 21 ratio
so 12 photos on one side, and 21 on the other side to get the ratio of 4 to 7
