Answer: 31x - 35

Let’s start by rewriting the equation

-9x+5(8x-7)

Now let’s distribute

-9x+5(8x-7)

-9x+40x-35

Now we need to combine like terms. These are numbers that share the same variable, or lack of.

-9x + 40x -35

31x - 35

Since there is no equal sign, this is as simplified as this equation can get. If you need more help feel free to comment below :)

Answer:

distribute the +(positive) 5 to the numbers in the parenthesis (8x-7) and solve it from there! it is left as an expression, because you can't add a variable with an integer

Explanation:

5*8x=40x

5*-7= -35

so it's: -9x+40x-35 which also equals 31x-35
