$x^{2}$ = 10 + $\frac{36}{10}$ $y^{2}$

The correct answer choice is A.

Step-by-step explanation:

10 $x^{2}$ - 36 $y^{2}$ = 100

By isolation 10 $x^{2}$ you are adding 36 $y^{2}$ to both sides.

With this step we are left with this result:

10 $x^{2}$ = 100 + 36 $y^{2}$

Finally, we can simplify the equation further by dividing all terms by the coefficient 10, since it was what $x^{2}$ was multiplied by.

$x^{2}$ = 10 + $\frac{36}{10}$ $y^{2}$
