Question

solve the equation x2=15

Answer 1

x=15/2=7.5
x=7.5
you just need to divide 15 for the number next to the x

Answer 2

The answer is $x = 15/2$

Here's how I got my answer:

Step 1: Re-arrange the equation to $2x = 15$

Step 2: Divide both sides by 2. Which leaves us with our answer, $x = 15/2$

The decimal form of $15/2$ is 7.5 if you need that.
