Question

are the following pairs of linear equations coincident? justify your answer 3 x minus 4 y = 12 and 4 x + 3 y equal to 12​

Answer 1

Answer:

The given pair of linear equations are not coincident.

Step-by-step explanation:

If a pair of lines are coincident, then they must have infinitely many solutions.

Condition for infinitely many solutions is:

a1/a2 = b1/b2 = c1/c2

Here, for the given two linear equations —

3/4 = -4/3 = 12/12 which does not satisfy the above condition.

Hence the given pair of linear equations do not coincide.
