3ab - 2bc = 12 Solve for c.

Question

I need help with this equation. Please list the steps to solve them.

Answer 1

Hi Super,

 

The trick is to get C on one side of the equation by itself:

 

3ab - 2bc = 12

 

3ab - 12 = 2bc

 

Now divide both sides by 2b

 

(3ab - 12) / 2b = c

 

Distribute the 2b

 

(3ab / 2b) - (12 / 2b) = c

 

From left to right: divide 3 by 2, cancel the b, and divide 12 by 2

 

Now we have our answer!

 

(3a/2) - (6/b) = c

 

Great question! Give me a thumbs up if I helped!

Answer 2

To solve for c, we want to isolate the c terms.

 

Subtract 3ab on both sides of equation.

 

-2bc = 12 - 3ab

 

 

Divide both sides of equation by -2b.

 

c = (12 - 3ab) / (-2b)

 

c = (-6/b) + (3a/2)
