Question

Solve the fillwoing pair of linear equations grahically 2x+y=5andx+y=4​

Answer 1

Answer:

x is 3 and y is 1 hope you got your answer

Answer 2

2x+y = 5 (i)

x+y = 4 (ii)

2x+y = 5

=) 2x = 5-y

=) x = (5-y)/2

Putting the value of x in equation (ii)

x+y = 4

=) (5-y)/2+y = 4

=) (5-y+2y)/2 = 4

=) 5+y = 2×4

=) y = 8-5

=) y = 3

Putting the value of y in equation (i)

2x+y = 5

=) 2x+3 = 5

=) 2x = 5-3

=) 2x = 2

=) x = 2/2

=) x = 1

Ans:- x = 1 ; y = 3
