–7–5w–7w=5–9w

Sure, let's solve the equation step by step:

–7–5w–7w=5–9w

First, combine like terms on both sides of the equation:

-5w - 7w = -12w on the left side and -9w on the right side.

So, the equation becomes:

-7 - 12w = 5 - 9w

Next, let's isolate the variable terms on one side and the constant terms on the other side.

To do this, add 9w to both sides of the equation:

-7 - 12w + 9w = 5 - 9w + 9w

This simplifies to:

-7 - 3w = 5

Then, add 7 to both sides of the equation:

-7 - 3w + 7 = 5 + 7

This simplifies to:

-3w = 12

Finally, divide both sides by -3 to solve for w:

w = 12 / -3

So, w = -4.
