-2x2 + y = 4

Solving for variable 'x'.

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

Add '-1y' to each side of the equation.
-2x2 + y + -1y = 4 + -1y

Combine like terms: y + -1y = 0
-2x2 + 0 = 4 + -1y
-2x2 = 4 + -1y

Divide each side by '-2'.
x2 = -2 + 0.5y

Simplifying
x2 = -2 + 0.5y

Reorder the terms:
2 + x2 + -0.5y = -2 + 0.5y + 2 + -0.5y

Reorder the terms:
2 + x2 + -0.5y = -2 + 2 + 0.5y + -0.5y

Combine like terms: -2 + 2 = 0
2 + x2 + -0.5y = 0 + 0.5y + -0.5y
2 + x2 + -0.5y = 0.5y + -0.5y

Combine like terms: 0.5y + -0.5y = 0.0
2 + x2 + -0.5y = 0.0
