Question

7x-3y +16=0 and 21x-9y+48=0 is consistent or not
​

Answer 1

Answer:

it is CONSISTENT

Step-by-step explanation:

let a1=7 , a2=21

b1=-3 , b2=-9

c1=16 , c2=48

so when we divide a1/a2 and b1/b2 and c1/c2

we will get a1/a2 = b1/b2 = c1/c2 =1/3

since all the ratio are equal then then the roots are coinsides on a same line

So, Therefore the equations is consistent
