joy added 26 new contacts to her phone list. She now has a total of 100 contacts. Let c represent how many contacts joy had on her phone list before she udpated it. write an equation and solve for c.
Step-by-step explanation: To find what c equals, we must flip the solution around and subtract it. When we take 100 - 26, we get 74. Therefore, c = 74. I hope this helped! :)
