Thank you for the opportunity to help you with your question!

a linear equation is any equation that can be expressed in the form ax+b=0 where a and b are real numbers and x is a variable.Expressing a function in this form is known as standard form of linear equation

There we start by expressing  our function

NOTE:

KINDLY THERE IS CONFUSION ON THE QUESTION.BECAUSE YOU HAVE WRITTEN TWO DIFFERENT FUNCTIONS ie

5/x-2/y=7 and  

5/x - 2/7=7



Please let me know if you need any clarification. I'm always happy to answer your questions.

Hi.This a continuation to  our above function on expressing in linear standard form

for 5/x-2/7=7,

we start by collecting the like terms together ie. we move 2/7 to right hand side of the equal sign and when -ve cross equal sign it becomes +ve

5/x=7+2/7 , find the common denominator and add the two as fraction

5/x=7/1+2/7 common factor is 7, therefore we have 

5/x=49/7+2/7

5/x=51/7

lets multiply  by x on both side to eliminate it from the denominator

x*5/x=51/7*x

5=51/7(x)

linear equation is equation of form ax+b=0

therefore, rearranging by taking 5 to the RHS of the equation, we obtain

51/7(x) -5=0

Since the function corresponds to the linear equation form hence its a linear equation
