-1a + 2c + x2 = 0

Solving for variable 'a'.

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

Add '-2c' to each side of the equation.
-1a + 2c + -2c + x2 = 0 + -2c

Combine like terms: 2c + -2c = 0
-1a + 0 + x2 = 0 + -2c
-1a + x2 = 0 + -2c
Remove the zero:
-1a + x2 = -2c

Add '-1x2' to each side of the equation.
-1a + x2 + -1x2 = -2c + -1x2

Combine like terms: x2 + -1x2 = 0
-1a + 0 = -2c + -1x2
-1a = -2c + -1x2
