Question

How many solutions have the pair of
have the pair of linear equations
9x+3y=12,18+6y=24​

Answer 1

Answer:

Step-by-step explanation:

9x +3y = 12 => 9x +3y -12 =0

18x +6y =24=> 18x +6y -24 =0

a₁/a₂ = 9/18 = 1/2   b₁/b₂ = 3/6 = 1/2   c₁/c₂= -12/-24 =1/2

as a₁/a₂ = b₁/b₂ = c₁/c₂ = 1/2

therefore the equations have infinitely many solutions
