What equation matches this situation?
Robyn had some video games then bought 4 more.  Now she has a total of 10 games.

• v - 4 = 10
• v + 4 = 10
• 10 - 4 = v
• Answer not Given

• multiply both sides by 5
• add 5 to both sides
• divide both sides by 5
• subtract both sides by 5

v/5  =  9

• v = 45
• v = 40
• v = 14
• v = 4
