6=\sqrt{\frac{10}{49}x}
Divide 2x by 9.8 to get \frac{10}{49}x.
\sqrt{\frac{10}{49}x}=6
Swap sides so that all variable terms are on the left hand side.
\frac{10}{49}x=36
Square both sides of the equation.
\frac{\frac{10}{49}x}{\frac{10}{49}}=\frac{36}{\frac{10}{49}}
Divide both sides of the equation by \frac{10}{49}, which is the same as multiplying both sides by the reciprocal of the fraction.
x=\frac{36}{\frac{10}{49}}
Dividing by \frac{10}{49} undoes the multiplication by \frac{10}{49}.
x=176.4
Divide 36 by \frac{10}{49} by multiplying 36 by the reciprocal of \frac{10}{49}.
