Asked by Ariana
write an equation to solve each problem
Briana and her sister Molly want to buy the same model bicycle. Briana needs $73 more before she can afford the bike. Molly needs $65 more. If they combine their money, they will have just enough to buy one bicycle that they could share. What is the cost of the bicycle?
*Could you show me the work on how to do it

cost = c
Briana + 73 = c
Molly + 65 = c
Briana + Molly = c
so molly = (c - Briana)
now we have
Briana + 73 = c
(c - Briana) + 65 = c or Briana = 65
Briana + 73 = c
73 + 65 = c = 138
Briana + 73 = c
Molly + 65 = c
Briana + Molly = c
so molly = (c - Briana)
now we have
Briana + 73 = c
(c - Briana) + 65 = c or Briana = 65
Briana + 73 = c
73 + 65 = c = 138
