Question

4/x + 5/y = 4 is linear equation in two variables or no then why no justify​

Answer 1

An equation is said to be linear equation in two variables if it is written in the form of ax + by + c=0, where a, b & c are real numbers and the coefficients of x and y, i.e a and b respectively, are not equal to zero. For example, 10x+4y = 3 and -x+5y = 2 are linear equations in two variables.

Answer 2

Answer:

Yes

Step-by-step explanation:

4/x +5/y = 4

Cross multiplication.

5x + 4y / xy = 4

:. 5x + 4y = 4xy .

As x and y is having power 1 . Hence it is a linear equation.
