Answer
$6=2y-x$
Work Step by Step
In order to write the equation in standard form, we must get y and x on the same side of the equation:
$y -1/2x=3$
x, however, is being multiplied by 1/2. Because we want this equation to be in standard form using integers, we multiply both sides of the equation by 2 to obtain:
$6=2y-x$
