Question

The solution of the pair of linear eq. 2x-y=5 and 5x-y=11 is

Answer 1

hope this helps u

2x-y=5------------>eq1

5x-y=11------------->eq2

i have done  by substitution

from eq 2

y=5x-11

sub y=5x-11 in eq 1

2x-(5x-11)=5

2x-5x+11=5

-3x=5-11

-3x=-6

x= -6/-3

x=2

y=5x-11

= 5*2-11

y=10-11

y= -1
