Answer 1

Question

Which of the following is not linear equation?

A. x + y = 3

B. xy = 3

C. x- 2y=3

D. x - 7 = y

Answer

The equation whose exponent is one is called linear equation.The standard form of linear equation is ax+by = c

A. ( x + y = 3) is in the form of (ax+by = c), therefore it is a linear equation.

B. (xy = 3) is not in the form of (ax+by = c), therefore it is not a linear equation.

C.( x - 2y = 3) is in the form of (ax+by = c), therefore it is a linear equation.

D. (x - 7 = y) is in the form of (ax+by = c), therefore it is a linear equation.

Therefore, option B. is not a linear equation.
