How would i do 11w-9-7w=15 ?

First, you combine like-terms.

11w-9-7w=15
11w minus 7w is 4w

4w-9=15
add 9 to each side
4w=24
divide each side by 4
w= ?

To solve the equation 11w - 9 - 7w = 15, you need to combine like terms and then isolate the variable w.

Step 1: Combine like terms
Combine the terms with the variable w on one side by subtracting 7w from both sides of the equation:
(11w - 7w) - 9 = 15

Simplifying this, we get:
4w - 9 = 15

Step 2: Isolate the variable w
To isolate the variable w, you need to get rid of the constant term (-9) on the left side of the equation. You can do this by adding 9 to both sides:
4w - 9 + 9 = 15 + 9

This simplifies to:
4w = 24

Step 3: Solve for w
To solve for w, divide both sides of the equation by the coefficient of w, which is 4:
4w/4 = 24/4

Simplifying this:
w = 6

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