whenever you see an unknown number keep it as a letter , a variable ( like x, y etc.)

Let us say the number we are talking about is x

rajee_sam · Answer

times means multiplication

rajee_sam · Answer

5 times the number is 5x. Now this is decreased by two times the same number which is x

rajee_sam · Answer

decrease means subtract. 5x - 2x

rajee_sam · Answer

now solving is 5x - 2x = 3x

anonymous · Answer

So the answer is 5x-2x? Thanks God I asked. I had 5x-y^2

anonymous · Answer

Thanks guys :)

anonymous · Answer

yeah, I got it. Thanks - it's been so long ugh

anonymous · Answer

I just reread this question and it says to not simplify??
and then another answer is for it to be simplified. 
"type the expression using x as the variable - do not simplify"

anonymous · Answer

nevermind :)
