Answer:
The x and y intercept are (20,0)
Step-by-step explanation:
2x-4y=40—eqn1
-x+2y=-20—eqn2
Make x the subject of eqn2
-x=-20-2y
x=20+2y
plug this into eqn 1
2(20+2y)+4y=40
40+4y+4y=40
8y=40-40
y=0
plug y=0 into eqn2
-x+2(0)=-20
-x=-20
x=20
Answer:
Adult tickets=275
Step-by-step explanation:
form 2 equations from the given info.
x+y=611
y=x+61

x+x+61=611
2x+61=611
2x=550
x=275
