Question

Helpp whats the answer

5x=15

Answer 1

`\boxed{\tt x=3}`

Explanation:

We are given the equation:

`5x=15`

and asked to solve for
`x`. Therefore, we must isolate the variable on one side of the equation.

`x` is being multiplied by 5. The inverse of multiplication is division. Divide both sides of the equation by 5.

`(5x)/(5)=(15)/(5)`

`x=(15)/(5)`

`x=3`

Let's check our solution. Plug 3 in for x and solve.

`5x=15`

`5(3)=15`

`15=15`

This checks out, so we know our solution is correct.

The solution to 5x=15 is x=3.
