Question

The sum of nine times a number, and 4, is equal to eight times the number.

Answer 1

Explanation:

For this, we will use the variable x.

9x + 4 = 8x

4 = -1x

x = -4

If they are looking for just the formula, it is 9x + 4 = 8x

If they are looking for the solved answer, it is x = -4

Answer 2

-4

Explanation:

Let's put this in math notation. We can call the number x:

9x+4=8x

Subtract 8x from both sides:

x+4=0

Subtract 4 from both sides:

x=-4
