Given: Two equations, x + 2y = 3
⇒ x + 2y – 3 = 0 - - - - (1)
2x + 4y + 7 = 0 - - - - (2)
We know that the general form for a pair of linear equations in 2 variables x and y is a1x + b1y + c1 = 0
and a2x + b2y + c2 = 0.
Comparing with above equations,
we have a1 = 1, b1 = 2, c1 = - 3; a2 = 2, b2 = 4, c2 = 7
Since
a1/a2 = b1/b2≠c1/c2
