x^2-y^2=.36x^2

Solution for x^2-y^2=.36x^2 equation:

Simplifying
x2 + -1y2 = 0.36x2

Solving
x2 + -1y2 = 0.36x2

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-0.36x2' to each side of the equation.
x2 + -0.36x2 + -1y2 = 0.36x2 + -0.36x2

Combine like terms: x2 + -0.36x2 = 0.64x2
0.64x2 + -1y2 = 0.36x2 + -0.36x2

Combine like terms: 0.36x2 + -0.36x2 = 0.00
0.64x2 + -1y2 = 0.00

Add 'y2' to each side of the equation.
0.64x2 + -1y2 + y2 = 0.00 + y2

Combine like terms: -1y2 + y2 = 0
0.64x2 + 0 = 0.00 + y2
0.64x2 = 0.00 + y2
Remove the zero:
0.64x2 = y2

Divide each side by '0.64'.
x2 = 1.5625y2

Simplifying
x2 = 1.5625y2

Take the square root of each side:
x = {-1.25y, 1.25y}
