Question

2/y+5/x=9
4/y+3/x=11,(xy≠0)
Solve the given system of equation using cramer's rule.

Answer 1

Answer:

x = 1

y = 1/2

Step-by-step explanation:

2/y+5/x=9    - eq 1

4/y+3/x=11  -  Eq 1

2 * Eq 1  - Eq 2

= 4/y + 10/x  - ( 4/y + 3/x) = 18 - 11

=> 7/x = 7

=> x = 1

2/y  + 5/1  = 9

=> 2/y = 4

=> y = 2/4

=> y = 1/2
