So first you would subtract 10 from both sides then you would have 90-10 which is 80 so w is equal to 80

10 * w = 90             m - 15 = 20             Hope this helps you!! :)
                                     +15   +15
10w = 90                       ----   -----
-----     ----                       m = 35
10       10

w = 9
