Answer:

[tex]w= 37[/tex]

Step-by-step explanation:

The student used the wrong property of equality.

When you undo a number to get a letter by itself, you should do the opposite operation of the number said. The student subtracted 15 from 22 instead of adding 15 to 22.

Use the addition property of equality to isolate w.

[tex]w(-15+15)=22+15\\w=37[/tex]
