Question

-(14 – 9c) = 4(2c + 5) what is the answer

Answer 1

c=34

Explanation:

So, our starting equation is: -(14 – 9c) = 4(2c + 5)

and this is how we can solve it:

We move all terms to the left:

-(14-9c)-(4(2c+5))=0

We add all the numbers together, and all the variables

-(-9c+14)-(4(2c+5))=0

We get rid of parentheses

9c-(4(2c+5))-14=0

We calculate terms in parentheses: -(4(2c+5)), so:

4(2c+5)

We multiply parentheses:

8c+20

Back to the equation:

-(8c+20)

We get rid of parentheses:

9c-8c-20-14=0

We add all the numbers together, and all the variables:

c-34=0

We move all terms containing c to the left, and all other terms to the right:

c=34

I know it looks complicated but I do hope this helps! :)
