Question

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

Answer 1

Answer:

-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
