Answer: W=-4

Explanation:
Add the W together on the left
Add 12w to both sides
Subtract 5 from both sides
End up with -12=3w
Divide both sides by 3
End up with the answer of W=-4
-7-5w-7w=5-9w

First collect like terms on the left side
-7-12w=5-9w
Now bring the -7 +7 +7
to the right side Now since -7 + 7 is zero,
It cancels out, 5 + 7 is 12!



-12w = 12 -9w
+9 +9
Now, bring -9 to the -9 + 9 cancels out
left side

-12 + 9 is -3



-3w = 12

Lastly, dived -3 by 12

W = -4
