Question

is the pair of equations x-y=5 and 2y-x=10 inconsistent? Justify your answer
​

Answer 1

Answer:

no

Step-by-step explanation:

x-x=o, -y+2y=y, 5+10=15

y=15

x-15= 5

x=20

Answer 2

Answer:

x-y=5

2Y-x=10

a1/a2=1/2 b1/b2=1/1 c1/c2=5/10

a1/a2 is not equal to b1/b2

hence it is a intersecting

so it is inconsistent
