You solve the two equations simultaneously. There are several ways to do it; one method is to solve the first equation for "x", then replace that in the second equation. This will give you a value for "y". After solving for "y", replace that in any of the two original equations, and solve the remaining equation for "x".You solve the two equations simultaneously.

It is not possible to solve one linear equation in two unknown variables.
Do sin(x), square it, and then multiply it by two.
It is generally not possible to solve a single equation in two variables: this is one such.

Solve sin² x = sin x. The answer is x = 0 or π/2 or π. Here's how you can find this result: Let s = sin x. Then, we have, s² - s = 0; whence, s(s - 1) = 0. Now, when the product of two numbers is zero, then one or other of them must equal zero. Hence, either, s = 0 OR s - 1 = 0; that is, sin x = 1 or 0. For 0 ≤ x < 360°, x = 0° or 90° or 180°; those being the only angles whose sine equals either 1 or 0. In term of radian measure, x = 0 or π/2 or π.

X2 - Y2 = (X + Y)(X - Y)
You can't solve it - you only have one equation and two unknowns. You need 2 equations to solve this.
X + Y = 22 X - Y = 4 add equations: 2X = 26 solve X X = 13 solve Y Y = 9
