Question

Can someone check my answer? Please and Thank You!!! solve for the following equation:

-5(-3x+5)= -5+5x

I got x=2, is this right?

Answer 1

well, let's show you how to check it

Answer 2

Well you can check be plugging in 2 where x is in the problem!

\(\sf \large \color{magenta}{-5(-3x~+~5)~= ~-5~+~5x}\)

\(\sf \large \color{magenta}{-5(-3*2~+~5)~= ~-5~+~5*2}\)

Answer 3

if you insert x=2 anywhere you see an x, do you get the same thing on both sides?

Answer 4

yes :) I thought that would be how you check it

Answer 5

indeed, then you are correct if it works

Answer 6

(which it does)

Answer 7

Let's start doing the left side

\(\sf \large \color{magenta}{-5(-3*2~+~5)~}= ~-5~+~5*2\)

We have to start doing the parenthesis first! We gotta make sure we follow the PEMDAS rules!

As we look in the parenthesis, we have multiplication and addition. Next step in the PEMDAS is Multiplication/Division, so we do the multiplication first!

So what is -3*2?
