the answer is that you subbtract 3y from both sides sence you are solving for x
I think the correct answer among the choices listed above is option A. The first step in solving the equation 3y + x = 6 for x is to Subtract 3y from both sides of the equation. Solving for x is as follows:
3y + x = 6
3y + x - 3y = 6 - 3y
x = 6 - 3y
3y + x = 6
3y + x - 3y = 6 - 3y
x = 6 - 3y
