The standard form for writing a linear equation is:
Ax + By = C
wherein:
A is positive
A and B shouldn't be both zero
A, B, and C should be integers
The equation is in its simplest form
The equation is free from fractional coefficients.
(4x + 3x) = (2y - 5)
7x = -3y
The standard form is 7x + 3y = 0.
