yes they are colsistent
2x+y-5=0
2x+y=5
y=5-2x (1)
2x=5-y (2)

Answer:
Both graphs intersect at x = 2 , y = 1
pair of equations is consistent
Step-by-step explanation:
x 2x+y-5=0 3x-2y-4=0
-4 13 -8
-3 11 -6.5
-2 9 -5
-1 7 -3.5
0 5 -2
1 3 -0.5
2 1 1
3 -1 2.5
4 -3 4
Both graphs intersect at x = 2 , y = 1
hence one solution exist
hence the pair of equations is consistent and independent
