Question

solve the following by cramer's rule
2x+3y=2;x-y/2=1/3​

Answer 1

Answer:

2 x + 3 y = 2 --------1' x - y = 2 /3----------2

3 x - 3y = 2 --------3 from equation 2

add equation 1 and 3

5 x = 4 ===== x = 4/5

from equation 2,4/5 - y = 2/3

======== - y = 2/3 - 4/5

=== y = 4 /5 - 2/3

=== y = 2 / 10

=== y = 1/5
