Basic Math Examples

$- 2 = 2 u + 2$

Step 1

Rewrite the equation as

$2 u + 2 = - 2$ .

$2 u + 2 = - 2$

Step 2

Move all terms not containing

$u$ to the right side of the equation.

Step 2.1

Subtract

$2$ from both sides of the equation.

$2 u = - 2 - 2$

Step 2.2

Subtract

$2$ from

$- 2$ .

$2 u = - 4$

$2 u = - 4$
