The standard form using integers is x + 3y = 0
Solution:
Given that we have to write the given equation 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
Let us convert the given equation to standard form
Given equation is:

Multiply the terms inside bracket with constant outside the bracket in right hand side of equation

Simplify the right hand side of equation

Move the 3 from R.H.S to L.H.S

Move the terms from R.H.S to L.H.S

Thus the standard form is found
