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 :)
