Question

The difference of three times a number and eight is seven. Find the number.

Answer 1

x= 5

Explanation:

The problem can be translated into the equation:

3x - 8 = 7

Now, you want to isolate the variable "x" on one side of the equation.

First, add 8 to both sides of the equation to get rid of the -8 on the left side:

3x - 8 + 8 = 7 + 8

This simplifies to:

3x = 15

Next, to solve for "x," divide both sides by 3:

3x / 3 = 15 / 3

This simplifies to:

x = 5

So, the number you're looking for is 5.
