Question

10) Which of these is linear equation in two variables? A) 5x-2y-0 b) x+x²-2y+8=0 c) x-2y+10=x²+y d) 3x-2y²+1=0​

Answer 1

Answer:

A) 5x-2y-0 is linear equation in two variables.

Because it is in the form of ax +by +c=0 where, a, b and c are the real numbers and x and y are the variables.

Answer 2

Given:  A) 5x-2y-0  b) x+x²-2y+8=0  c) x-2y+10=x²+y  d) 3x-2y²+1=0​

To find:  Which of these is a linear equation in two variables

Solution:

For a linear equation to have only two variables, it should be in the form ax^2+bx+c=0

Here, a and b are two variables are c is the real number.

The correct answer will be  A) 5x-2y-0.
