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
KINDLY THERE IS CONFUSION ON THE QUESTION.BECAUSE YOU HAVE WRITTEN TWO DIFFERENT FUNCTIONS ie
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
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
lets multiply by x on both side to eliminate it from the denominator
linear equation is equation of form ax+b=0
therefore, rearranging by taking 5 to the RHS of the equation, we obtain
Since the function corresponds to the linear equation form hence its a linear equation
