#color(blue)(x=3#

#−3x+7=3x−11#

#7+11=3x+3x#

#18=6x#

#18/6=x#

#color(blue)(x=3#

To solve -3x + 7 = 3x - 11, first, you need to isolate the variable x. Start by moving all terms involving x to one side of the equation and constants to the other side. Then, combine like terms and solve for x.

Add 3x to both sides:

-3x + 3x + 7 = 3x - 3x - 11

This simplifies to:

7 = 6x - 11

Add 11 to both sides:

7 + 11 = 6x - 11 + 11

This simplifies to:

18 = 6x

Finally, divide both sides by 6:

18 / 6 = 6x / 6

This simplifies to:

3 = x

So, x = 3.

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.
