Answer:
-5 - 4x
Step-by-step explanation:
First distribute the -3.
7 - 3 (4 - 2x) - 10x = 7 - 12 + 6x - 10x
Subtract 12 from the 7 at the front of the expression.
7 - 12 + 6x - 10x = -5 + 6x - 10x
Now subtract the 10x from the 6x at the back of the expression.
-5 + 6x - 10x = -5 + -4x
-5 + -4x = -5 - 4x
Have a nice day and mark brainliest if possible :)
