Question

What is the result of isolating x^2 in the equation below? 10x^2-36y^2=100???? please help

Answer 1

`x^2=10+(18y^2)/(5)`

Explanation:

If you really want to get x^2 by itself the first step is to add 36y^2 on both sides giving you:

`10x^2-36y^2=100`

`10x^2-36y^2+36y^2=100+36y^2`

`10x^2+0=100+36y^2`

`10x^2=100+36y^2`

Now you divide both sides by 10:

`x^2=(100+36y^2)/(10)`

You could separate the fraction:

`x^2=(100)/(10)+(36y^2)/(10)`

You can reduce both fractions:

`x^2=10+(18y^2)/(5)`

Answer 2

first isolate 10x^2
10x^2 = 36y^2 + 100
Divide both sides by 10
x^2 = 3.6y^2 + 10
