Answer:

A(1,1)

Explanation:

the system is :

2x-y=1

x+2y=3

so :

y = 2x-1 .....the line color : red

y= (-1/2)x+3/2......the line color : blue

the pair solution is the intersection point for this line : A(1 ; 1)

Check graphically whether the pair of equations 2x-y=1 and x+2y=3 is consistent if-example-1
