Question

2/x-3/y=15; 8/x+5/y=77

Answer 1

Step-by-step explanation:

2/x-3/y=15; 8/x+5/y=77

• We need to solve the simultaneous equation
• Given 2/x – 3/y = 15
•          8/x + 5/y = 77
• Multiplying the first equation by 4 we get
•       8/x – 12/y = 60
•       8/x + 5/y = 77
• Subtracting we get
•           -12 / y – 5/y = - 17
•         -17 / y = - 17
• Or y = 1
• Now 2/x – 3/1 = 15
• 2/x = 18
• 18 x = 2
• Or x = 1/9.
