Answer:

Step-by-step explanation:

let number of adult tickets=x

and number of student tickets=y

x+y=137   ...(1)

8x+6y=952

divide by 2

4x+3y=476   ...(2)

multiply by 3

3x+3y=411   ....(3)

(2)-(3) gives

x=65

y=137-65=72

number of adult tickets=65

number of student tickets=72

2.

let number of rose flowers =x

and number of carnation flowers=y

x+y=264

y=264-x

3.50 x+2.50y=772

multiply by 2

7x+5y=1544

7 x+5(264-x)=1544

7 x+1320-5 x=1544

2 x=1544-1320

2 x=224

x=112

y=264-112=152

number of rose flowers=112

number of carnation flowers=152
