Question 828307: You and your friend are selling raffle tickets for a new laptop. You sell 14 more tickets than your friend sells. Together, you and your friend sell 58 tickets.
a. Write a system of linear equations that represents this situation.
b. How many tickets do each of you sell? Answer by TimothyLamb(4379) (Show Source):
You can put this solution on YOUR website! ---
x = you sold
y = friend sold
---
x + y = 58
x = y + 14
---
put the system of linear equations into standard form:
---
x + y = 58
x - y = 14
---
copy and paste the above linear system in standard form into this matrix-method solver:
