Answer 2

Concept: Concept: associate equation is claimed to be equation in two variables if it's written inside the sort of ax + by + c=0, where, b & c unit of measurement real numbers and so the coefficients of x and y, i.e. and b severally, are not up to zero.

If (a1/a2) = (b1/b2) ≠ (c1/c2), then there'll be no answer.

This type of system of equations is named associate inconsistent try of linear equations. If we tend to plot the graph, the lines are going to be parallel and system of equations don't have any answer.

Given: x-4y=2 and 3x+cy=10

Find: Calculate the value of c.

Solution: If equation has no solution.

a1/a2 = b1/b2 ≠ c1/c2

1/3 = -4/c ≠ 2/10

c= -12 and c≠ -20

Final answer: c can be -12 but cannot be -20.
