Which equation is in standard form?

3x+4y=103x+4y=10

19+3y=2x19+3y=2x

7y-7x=87y-7x=8

8+5x=3y

3x+4y=10 is in standard form. The standard form is Ax+By=C and this equation suits that form with A as 3, B as 4, and C as 10.

Standard form is ax+by=c where a, b, and c are integers and a is never negative

see all of them

first one

3x+4y=10

nothing wrong

2nd one

19+3y=2x

wrong, x and y have to be on same side

3rd one

7y-7x=8

x has to be positive

4th one

8+5x=3y

x and y have to be on the same side

answer is the first one: 3x+4y=10
