What is the result of isolating x^2 in the equation below 10x^2-36y^2=100
aniked [119]
For the answer to the question above,
<span>10x^2-36y^2=100
Then isolate x^2, first add 36y^2 to both sides: 10x^2 = 100 + 36y^2 divide both sides by 10:
x^2 = 10 + 3.6y^2 or
10 + 36/10 * y^2 = 10 + 18/5 * y^2
</span>
So the answer to this question is
<span><span>x2</span>=10 + (<span>18/5)</span><span>y2

I hope my answer helped you. Have a nice day!</span></span>
