Is x+(-y) equal to x-y?
If it makes a difference, y is equal to 5, and x is not used here to represent a number. it's actually just 'x'.
Yes because a positive and a negative makes a negative
Examples:Adding & Subtracting1) x + (-y) = x - y2) x - (-y) = x + y3) -x + y = y - xMultiplying & Dividing1) x(-y) = -xy2) (-x)(-y) = xy3) (-x)y = -xy4) x/(-y) = -x/y5) (-x)/(-y) = x/y6) (-x)/y = -x/y
