Let's call the number "x".
The equation can be written as:
2(x + 9) = 3(x - 9)
Now let's solve for x:
2x + 18 = 3x - 27
Subtract 2x from both sides:
18 = x - 27
Add 27 to both sides:
45 = x
Therefore, the number is 45.
write the following as an equation. then solve.
twice the sum of a number and 9 is equal to three times the difference of the number and 9. find the number
