Answer:3x1
Step-by-step explanation:
1. x = cost of one adult ticket
y= cost of one child ticket
2x+3y=31.60
x+2y=18.60 l multiply by -2
2x+3y=31.60
-2x-6y=-37.2
-3y=-5.6
y=1.87
2x+3(1.87)=31.60
2x+5.6=31.60
2x=31.60-5.6
2x=26
x=26/2
x=13
Answer: The adult ticket is $13 and the child ticket is $1.87
Step-by-step explanation:
red one has 108
then green one has 108/2
then m=54
Answer:
- 
Step-by-step explanation:
= 
( cross- multiply )
6x = 5y ( divide both sides by 6 )
x = y
Then
← substitute x = y into the expression
= 
= 
= 
= 
× - 
= -
