    Before you solve for x, you need to simplify the equation, which becomes x^2*1/2=49.

    To solve for x, you would use order of operations, and multiply by sides by 2, which makes x^2=98. To find x, you find the square root of both sides, which gives you x= square root of 98. The square root of 98 is about 9.9, so 9.9 is your answer

    \[\frac{x^2}{2}=49 \]\[x=7 \sqrt{2} \]
