Answer:

don't come at me, i haven't done this in a while, so it might not be correct.

3.25 or 3 1/4

Step-by-step explanation:

3/4x + 5 - 7 + 1/2x

3/4x + 1/2x = 5/4 or 1 1/4

So put that back in, and now you have

1 1/4x - 5 - 7

aaaaaaaand 5 - 7 = -2

so then you plug that back in

1 1/4x - -2 which would turn into 1 1/4x + 2 because two negatives make a positive
