To solve the equation 11w - 9 - 7w = 15, you first need to combine like terms, which means adding or subtracting the coefficients of similar terms. Then, isolate the variable w by performing inverse operations to both sides of the equation to solve for w.

Starting with the equation:

11w - 9 - 7w = 15

Combine like terms:

(11w - 7w) - 9 = 15

4w - 9 = 15

Now, isolate the variable w by adding 9 to both sides of the equation:

4w - 9 + 9 = 15 + 9

4w = 24

To solve for w, divide both sides of the equation by 4:

4w / 4 = 24 / 4

w = 6

Therefore, the solution to the equation 11w - 9 - 7w = 15 is w = 6.

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.
