You cannot add them. The 'y' in the 4xy means that you cannot add it to 3x, since the 'y' is an extra component that the 'x' does not have. You can add 3x to 3x, or 4y to 4y, but you cannot add terms which contain different variables to each other. (It's like trying to add apples and Oranges, they're not the same thing).
(x + 3)(x + 4y)
2y + 2xy' + 4y + 4xy' = 0 6y + 6xy' = 0 y' = -y/x
3x + 2 = 3x + 6 This is not possible.
(2, -1)
Their graphs are.
(x + 3)(x + 4y)
2y + 2xy' + 4y + 4xy' = 0 6y + 6xy' = 0 y' = -y/x
no
3x + 2 = 3x + 6 This is not possible.
3x plus 9 equals what?
(2, -1)
Their graphs are.
4x plus 7 plus 3x equals 19 plus xx = 2
what is a slope
2x+3x = 5x
y=4x2+3x+8
