Step-by-step explanation:
let's start with 5(2x+7)
first you need to multiply 5 by 2x which = 10x
then multiple 5 by 7 which =35
That's 10x+35
The second part is -3(x+5)
-3 by x= -3x
-3 by 5= -15
So that becomes -3x-15
Put everything together and it's 10x+35-3x-15
First you do 35-15=20
Then 10x-3x=7x
the answer is 20+7x or 7x+20 (pretty sure it's kind of hard to do this typing out)
