For other ppl looking at this question here's the answer.
First you have to put $x+8$ and $2x-1$ equal
Like this $x +8=2x-1$
Then you have to get x on one side
So Add 1 to both sides which cancels out the $-1$
And you have $x+9=2x$ left
Then subtract x from both sides
And you get $x=9$ .
hope this helps you; if you need help pm me :).

You have to first get the x by its self by canceling it out so subtract 3 and what you do to one side you do to the other. so that means that -3(-3) two negatives = a positive so thats 6 so what you should have now is x+6

What is the expression for "the difference between 5 times a number and twice that number"?

ycow [4]

Hey there :)

Before translating the sentence into mathematics, let r represent 'a number'

5 times a number = 5r
2 times that number = 2r

The difference between them = 5r - 2r

* Your equation
5r - 2r

* Solving the equation
= 5r - 2r
= 3r
