Yes, you need help
2 x/5 + y = -3
multiply BOTH sides by 5
2 x + 5 y = -15
2 x/5 + y = -3
multiply BOTH sides by 5
2 x + 5 y = -15

you are incorrect. As you correctly remembered, the standard form is
Ax + By = C
You multiplied the x and y by 5, but forgot the -3.
A is the correct choice.
Ax + By = C
You multiplied the x and y by 5, but forgot the -3.
A is the correct choice.
