find three consecutive integers such that three times the first minus the second is one more than third
---
1st: x
2nd: x+1
3rd: x+2
---
Equation:
3(x) - (x+1)= x+3
3x-x-1 = x+3
2x -1 = x+3
x = 4
x+1 = 5
x+2 = 6
----------------
2. A number is two times the difference between eighteen and a number find the number
---
Let the number be "x":
x = 2(18-x)
x = 36 -2x
3x = 36
x = 12
