$675 (total tickets) $21 , x (# of $21 tickets) $27 , y (# of $27 tickets) x + y = 29 y = 29 - x now we can use one variable. (easier) 21x - 27y = 675 substitute y 21x + 27(29-x) = 675 21x + 783 - 27x = 675 -6x = 675 - 783 -6x=-108 6x=108 x=18 y = 29 - 18 y = 11 They bought 18 of $21 and 11 of $27

Don't worry, it is actually a really easy question. Here goes: it's a system of equations right? Therefore, you will need TWO equations for this one since we have two different ticket prices. For tickets with the price of $21 I will give it the variable "x" and for tickets with the price of $27, I will give it the variable of "y" since these two are the easiest to use. Here are my TWO equations: 1.) 21x + 27y= 675 (multiply the number of tickets to there respectful price and then add them together to get the total cost of all the tickets, which is why it looks like i showed it above. We still don't know how many tickets were sold for $21 nor those sold at $27 so I will use the assigned variables I established earlier. We do know however, that between both, they make total of $675.) 2.) x+y=29 (We don't know how many of each tickets were sold, but we do know that between both sells, the baseball game had 29 tickets sold, which is why it looks like that equation.) Now comes the tricky part: We can't solve both unknown pieces of information, so we need to get rid of one variable in both equations. I will use the ELIMINATION METHOD to do so. It doesn't matter which one of the two you pick to get rid of. I will choose to eliminate "21x". To do this, I will multiply one equations by a -21! like this: -21(x+y=29) It doesn't matter which one you decide to multiply. NOTE: a negative and positive cancel each other out. The new result ends up giving you: 1.) 21x + 27y= 675 2.) -21x + -21y= -609 Next, you will have to combine like terms using both equations. I see that we can cancel the positive 21x and the negative 21x. If we had positive 27y with -21y, we are left with positive 6y. Finally we have 675 + -609. After we combine them, we are left with positive, so your new and only equation reads: 1.) 6y=66 (Now we do simple algebra by dividing 66 by 6. So now we know that y= 11. So now we have the number of tickets purchased at the price of $27.) Substitute 11 into the "y" of the second equation and you get this: x+ (11)= 29 (You should know what to do from here and you should end up with this: x=18, y=11 Simple huh?
