Question

Q.
Solve the following equations (SPECIAL CASE):
1. 103x + 51y = 617;
97x + 49y = 583
2.
23x - 29y = 98; 29x - 23y = 110​

Answer 1

Answer:

1. Add 1st and 2nd equation, it will give you 2x+y=12.

y=12-2x, put it 2nd equation, x = 12*49 - 583 = 5 and y = 2

2. Subtract 1st from 2nd equation, x+y = 2, x = 2 - y

Put it in second equation, y =-1 and x =3.
