2 + -2x + -1x2 = 11 + 4x + 3x + -1x2

Combine like terms: 4x + 3x = 7x
2 + -2x + -1x2 = 11 + 7x + -1x2

Add 'x2' to each side of the equation.
2 + -2x + -1x2 + x2 = 11 + 7x + -1x2 + x2

Combine like terms: -1x2 + x2 = 0
2 + -2x + 0 = 11 + 7x + -1x2 + x2
2 + -2x = 11 + 7x + -1x2 + x2

Combine like terms: -1x2 + x2 = 0
2 + -2x = 11 + 7x + 0
2 + -2x = 11 + 7x

Solving
2 + -2x = 11 + 7x

Solving for variable 'x'.
