Mathematics

Alinara [238K]3 years ago

Answer:

The letter "x" is often used in algebra to mean a value that is not yet known. It is called a "variable" or sometimes an "unknown". In x + 2 = 7, x is a variable, but we can work out its value if we try! A variable doesn't have to be "x", it could be "y", "w" or any letter, name or symbol.

Answer:

Step-by-step explanation:

45 + 2x - 5 = 180

2x + 40 = 180

2x = 140

x = 70

2(70) - 5 = 140 - 5 = 135

Suppose that there are two types of tickets to a show: advance and same-day. The combined cost of one advance ticket and one sam
xeze [42]
X = advance 
y= same day 

x+y=70

30x+15y=1650

--------------------------
  30x+15y=1650    
- x+y=70               (x15) -> 15x+15y=1050
--------------------------
 30x+15y=1650 
-15x+15y=1050
--------------------------
15x=600
x=600/15
x=40


so now u can insert the price of x AKA the price of the advanced ticket to find our the price of the same day ticket. 

x+y=70
so 
 40+ y=70 
y=70-40
y=30


x = advance =40
y= same day =30
