Step-by-step explanation:
Given 39x+41y=76;41x+39y=84
- Now we need to solve the given simultaneous equation.
- 39 x + 41 y = 76 ----------------1
- 41x + 39 y = 84----------------2
- Multiplying equations 1 and 2 by 41 and 39 we get
- 1599x + 1681 y = 3116
- 1599x + 1521 y = 3276
- So subtracting we get
- 160 y = - 160
- Or y = - 1
- Also 39 x + 41 (- 1) = 76
- 39 x – 41 = 76
- 39 x = 76 + 41
- 39 x = 117
- Or x = 117 / 39
- Or x = 3
