Question

find X in equation
$2x - 2 = 0$
and verify it

Answer 1

Simplifying
2x + 2 = 0

Reorder the terms:
2 + 2x = 0

Solving
2 + 2x = 0

Solving for variable 'x'.

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

Add '-2' to each side of the equation.
2 + -2 + 2x = 0 + -2

Combine like terms: 2 + -2 = 0
0 + 2x = 0 + -2
2x = 0 + -2

Combine like terms: 0 + -2 = -2
2x = -2

Divide each side by '2'.
x = -1

Simplifying
x = -1
