Answer:-1/2x-2
Step-by-step explanation: To simplify this expression, we can combine like terms and express as a different, but equivalent expression:
We have 2 "x" terms: 1/4x and 3/4x. We are subtracting them, so the net "x" term is -1/2x.
We have 2 constant terms: -7 and -5. We are subtracting them, (and remember subtracting a negative number makes it positive) so the net constant term is -2.
Combining the two terms gives us -1/2x - 2 as our answer.
