Question

5•x+5 - (5x + 25)

Answer 1

Ohk you have to do what's in the parentheses ( ). so the first step you would have to multiply the negative sign with the 5x which you'll get -5x and then multiply (-) with 25 and you'll get -25 so now rewrite the whole equation agian so it'll be [5•x+5-5x-25] then you multiply 5•x and you'll get [5x+5-5x-25] and then the 5xs cancels out and 5-25 is -20. and if your wondering why it's a negative it's bc -25 is bigger so it takes the sign. hope this is helpful:)

Answer 2

Ok, so you have your equation, 5·x+5-(5x+25).
First, do the prathases, so you have, 5x+5-5x-25.(5·x also means 5x)
Now, you need to combine like terms, and through that the xs cancel out, so you are left with -20 as you answer.
