Question 243208: Three times a number, decreased by 8, is the same as twice the number, increased by 15.
Find the number.

The number is 'x'.
...
Turning the words into a formula, we have:
3x - 8 = 2x + 15
...
Adding 8 to both sides:
3x = 2x + 23
...
Subtracting 2x from both sides:
x = 23
...
Always check your work!
...
Does 3*23 - 8 = 2*23 + 15?
69 - 8 = 61
2*23 + 15 = 46 + 15 = 61
Yes.
