Option A
-x + 6y = 42 is the standard form
<u>Solution:</u>
Given that we have to write in standard form
The standard form of an equation is Ax + By = C
In this kind of equation, x and y are variables and A, B, and C are integers
Given equation is:
Let us convert the above equation into standard form
Make the denominator same in R.H.S
Solve the above equation
Move 6 from R.H.S to L.H.S
Bring all the terms to one side, leaving only constant on R.H.S
The above equation is of form Ax + By = C
Thus option A is correct
