How do you solve the two step equation #12-3x=6#?

Answer 1

See a solution process below:

Step 1) Subtract #color(red)(12)# from each side of the equation to isolate the #x# term while keeping the equation balanced:

#12 - color(red)(12) - 3x = 6 - color(red)(12)#

#0 - 3x = -6#

#-3x = -6#

Step 2) Divide each side of the equation by #color(red)(-3)# to solve for #x# while keeping the equation balanced:

#(-3x)/color(red)(-3) = (-6)/color(red)(-3)#

#(color(red)(cancel(color(black)(-3)))x)/cancel(color(red)(-3)) = 2#

#x = 2#

To solve the two-step equation 12 - 3x = 6, you first subtract 12 from both sides to isolate the term with the variable, yielding -3x = -6. Then, divide both sides by -3 to solve for x, resulting in x = 2.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
