21 + -1x = 3 + x + -1(x + -3)

Reorder the terms:
21 + -1x = 3 + x + -1(-3 + x)
21 + -1x = 3 + x + (-3 * -1 + x * -1)
21 + -1x = 3 + x + (3 + -1x)

Reorder the terms:
21 + -1x = 3 + 3 + x + -1x

Combine like terms: 3 + 3 = 6
21 + -1x = 6 + x + -1x

Combine like terms: x + -1x = 0
21 + -1x = 6 + 0
21 + -1x = 6

Solving
21 + -1x = 6

Solving for variable 'x'.

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