Question

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

Answer 1

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.
