Answer:
Let's call the number we're trying to find "x."
According to the information given, we can create an equation based on the problem statement:
"Twice the difference of a number and 3 is equal to three times the sum of the number and 4."
This can be represented as:
2(x - 3) = 3(x + 4)
Now, let's solve this equation for x:
2x - 6 = 3x + 12
Now, let's isolate x on one side of the equation. First, subtract 2x from both sides of the equation:
-6 = x + 12
Now, subtract 12 from both sides to isolate x:
-18 = x
So, the number is -18.
