-42x = 24

what is the first step in order to get this variable all alone?

x =  or x = -.5714

Step-by-step explanation:

First divide by -42 on both sides.

-42x = 24

/-42     /-42

Then you'll have this

x =  

Then you have to simplify the fraction, since this doesn't divide evenly.

You can do this by divide the numerator and denominator by like terms.

/ =

You can simplify it further by dividing the numerator and denominator by 3.

/ =

Because 7 is a prime number this is the farthest you can simplify. You can now move the negative to the numerator because the fraction is completely simplified.

b

if a was wrong then it has to be b it cant be c either because not all the y intercepts are the same!
