Eight more than double a number is nine

1 answer

The equation to represent the problem is:

8 + 2x = 9

Where x is the unknown number.

To solve for x, we first need to isolate it on one side of the equation.

8 + 2x = 9

Subtract 8 from both sides:

2x = 1

Finally, divide both sides by 2:

x = 1/2

Therefore, the unknown number is 1/2.
