-2/3w = 60
Your goal is to simplify your variable to w.
(Not sure if I worded that right, but let me help you solve this.)
First, you need to get rid of the denominator, which means you multiply both sides by 3.
-2/3w × 3 (cross canceling) = -2w
60 × 3 = 180
Now, you have -2w = 180.
You need to divide your variable by -2, which you must do to 180.
-2w ÷ -2 (cross canceling) = w
180 ÷ -2 = -90
Your answer is w = -90.
Hope this helps you! :)
