(adsbygoogle = window.adsbygoogle || []).push({}); 5x + 2y = 48 and 3x + 2y = 32 represents the money collected from the school concert tickets sales during 2 class periods. If x represents the cost for each adult ticket and y represents the cost for each student ticket, what is the cost for each adult ticket?

I'm fairly good at algebra.

5x + 2y = 48
3x + 2y = 32

10x + 4y = 96
-6x + -4y = -64
---------------
4x = 32
x=8

To find y, plugin 8 for the x in either equasion
40 + 2y = 48
2y = 8
y = 4

x=8
y=4

Cost of Adult ticket is $8
Cost of Student ticket is $4





Any others you need help on, post them.

no, You would do the multiplication first... 5*8 = 40, 2*4 = 8 Then you take the 40 and the 8 and add them, Multiply and divide first then add and substract.

actually

He is right, I-MilkShake-I. When solving algebraic equations you must go in the order known as the order of operations, which is:

1: Parentheses and Brackets
2: Exponents
3: Multiplication and Division
4: Addition and Subtraction

Also reffered to as PEMDAS or,
Parenthesis
Exponents
Multiplication
Division
Addition
Subtraction

You're just trolling, right? Are you actually implying that 40 + 8 does not equal 48?
