3x-y+7/11-8=0 and 2y+x+11/7=10. solve
Step-by-step explanation:
- 3x - y + 7/11 - 8 = 0
- 2y + x + 11/7 = 10
- 3x - y 8 - 7/11
- x + 2y = 10 - 11/7
- 3x - y = 88 - 7 / 11
- 33 x - 11 y = 81 ..............
- x + 2y = 70 - 11 / 7
- 7 x + 14 y = 59 ..............
- 462 x - 154 y = 1134
- 77 x + 154 y = 649
- 539 x = 1783
- x = 1783
- x = 1783/539
- x = 3.30
