what is the answer to the following equation, 2(5a+1)=2(a+1)

Question

I need to get this information asap, so i f you are willing please answer, THANK YOU!

Answer 1

2(5a + 1) = 2(a + 1)

 

First we can divide both sides of the equation by 2:

 

2(5a + 1) = 2(a + 1)

(2/2)(5a + 1) = (2/2)(a + 1)

5a + 1 = a + 1

 

Now we can subtract 1 from both sides of the equation:

 

5a + 1 = a + 1

5a + 1 - 1 = a + 1 - 1

5a = a

 

Now we can see that this statement (5a = a) , is only true if    a = 0    . However, if you can't see this straight away, then you can subtract 'a' from both sides of the equation:

 

5a = a

5a - a = a - a

4a = 0

 

Then you can divide both sides of the equation by 4:

 

(4a)/4 = 0/4

a = 0
