7(8x – 3) + x
use the distributive property to simplify the expression.

-57x+21 because you distribute the negative seven throughout ---> -7 times 8x which would be -56x. Then you multiply -7 and -3 to get a positive 21. you have a positive x left over and you combine the -56x and the positive x and you get -57x with the remaining 21 which cannot be combined. so all in all the answer is -57x + 21 im pretty sure
