Question

Which one of these equations is correctly written in Standard Form?

one over sevenx + y = −3

7x + 1.5y = −3

x + 7y = −21

−7x + y = −21

Answer 3

@MATTW20

Answer 4

x+7y = -21

Answer 5

How'd you get to that?

Answer 6

Not all books agree on this but based on your examples that is the only logical choice because on coefficients are fractions and the leading coefficient is not negative.

Answer 7

I kinda understand now, Thanks :)

Answer 8

The Standard Form for a linear equation in two variables, x and y, is usually given as
Ax + By = C
where, if at all possible, A, B, and C are integers, and A is non-negative, and, A, B, and C have no common factors other than 1.
