are you sure because im not @skullpatrol

skullpatrol · Answer

Yes, I am sure because if you add -3x to both sides of the equation then you will get your answer.

Given: $$3x + y = 1$$
Solve for y.
$$-3x+3x+y=-3x+1$$ $$0 +y=-3x+1$$
$$y=-3x+1$$

skullpatrol · Answer

This is known as the addition property of equality;
 where you are allowed to add the same real number to both sides of the equation.

skullpatrol · Answer

If a,b and c are any real numbers and a = b,

then 
a + c = b +c and
 c + a = c + b.

If the same number is added to equal numbers the sums are equal.
