when five is added to the number that is produced by doubling the number x, the result is equal to three times the number that is five less than x. what is the value of x.

First, we write this in to a equation: 2x+5=3(5-x)

2x+5=15-3x

-5 and 3x on both sides

5x=10

divide 5 on both sides

x=2

 

Hope that helps! smiley

but 2x should be on the right side too because when it says "that number" its refering to 2x so shouldnt 2x be on he right side too

Let the number = x
2x + 5 =3 *(x - 5)
2x + 5 =3x - 15 
x = 20
