Answer:
X=9
Y=-9
Step-by-step explanation:
3x - 4y =9
-3x +2y=9 cross 3x and - 3x since they're opposite ــــــــــــــــــــــــ
-4y +2y =9 +9
-2y =18
Y =-18/2
Y= -9
Replace y in the first equation:
3x - 4 (-9)=9
3x +36=9
3x = 27
X= 27/3
X= 9
Hope this helps you.. Good luck
Answer:
Reserved seats tickets = $20
General admission tickets = $12
Step-by-step explanation:
From the above question:
Let us represent
Reserved seats tickets = R
General admission tickets = G
Reserved seat tickets for a concert cost $8 more than general admission tickets. Hence,
R = G + 8
Five reserved seat tickets and 3 general admission tickets cost at total of $136. Hence,
5R + 3G = 136
So, we substitute G + 8 for R in the equation above
5(G + 8) + 3G = 136
5G + 40 + 3G = 136
5G + 3G = 136 - 40
8G = 96
Divide both sides by 8
8G/8 = 96/8
G = 12
Therefore the cost of one General admission ticket = $12
Since R = G + 8
R = $12 + $8
R = $20
Therefore, the cost of the reserved seats tickets = $20
