ANSWER
......

the pair of equations 5x-15y=8 and 3x-9y=2/5 has___NO ___solutions

Answer 2

Hey There!!

we have

$5x - 15y = 8......(1) \: where \: \\ a1 = 5\: \: b1= - 15 \: \: c1 \: = - 8 \: \: \: \\ \\ and \\ 15x - 45y - 2 = 0...(2) \\ where \: \\ a2 = 15 \: b2 \: = - 45 \: \: c = - 2$
Comparing both the equation -
for
a1 / a2 = 5/45= 1/9

for -

b1/b2 = -15/-45 = 1/3

for -

c1/c2 = -8/-2 = 4/1

Since we know ,
if the condition is -

a1/a2 is not equal to b1 /b2.

Then it will have unique solution

since the condition is opt for this Solution too
therefore it has unique solution


Hope this helps u!!
