Answer by algebrahouse.com(1659)   (Show Source):
You can put this solution on YOUR website! "The sum of twice a number, and 7, is equal to the sum of a number and 6. Find the number."
x = the number
2x + 7 = x + 6 {sum of twice a number and 7 is equal to sum of the number and 6}
2x = x - 1 {subtracted 7 from both sides}
x = -1 {subtracted x from both sides}
the number is -1
