please answer this question ​

Answer 1

Answer:

• (2x-3y=5)×3
• 6x-9y=15-----(1)
• 6x-9=15----------(2)
• when we subtract (1) from (2)
• We got x=0 &y=0
• so if x&y both are equal to zero it's was proved that these equations has infinite no of solutions

Answer 2

there in a pair of equations,

a1 = 2, a2 = 6, b1 = -3, b2 = -9, c1 = 5, c2 = 15

If a pair of equations has an infinite no. of solution,

a1/a2 = b1/b2 = c1/c2

So, 2/6 = 1/3

-3/-9 = 1/3

5/15 = 1/3
