Answer:
= 298/11
Step-by-step explanation:
3x + 5y = 2 | ×2 |
2x - 4y = 20 | ×3 |
6x + 10y = 4
6x - 12y = 60
____________--
22y = -56
y = -56/22
y = -28/11
3x + 5y = 2 | ×4 |
2x - 4y = 20 | ×5 |
12x + 20y = 8
10x - 20y = 100
_____________+
22x = 108
x = 108/22
x = 54/11
5x - y
= 5(54/11) - (-28/11)
= 270/11 + 28/11
= 298/11
