No.
x+y=8 y=-x+8 is not an inverse variation. However, y=8/x is an inverse variation or y varies inversely as x.
It is the property that equals plus equals are equals.

Yes, -8 plus plus 3 equals -5. The "plus plus" is equivalent to a positive sign, so -8 plus (+3) equals -5.
No, the equation 5x + 3 = 8y + 3 is not a direct variation. In direct variation, two variables are directly proportional to each other, meaning they can be expressed as y = kx, where k is a constant. In this equation, the constant term (3) on both sides means it is not a direct variation.
