What is - 2 (a+b) = - 2a - 2b

-2 (a+b) = -2a-2b

Equation is alway true

Rearrange:

Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation:

-2 * (a+b) - (-2*a-2*b) = 0

Step by step solution:

Step 1:

Equation at the end of step 1:

(0 - 2 • (a + b)) - (-2a - 2b) = 0

Step 2:

Equation at the end of step 2:

0 = 0

Step 3:

Equations which are always true:

3.1 Solve 0 = 0This equation is a tautology (Something which is always true)

Equation is alway true
