I assume you want to simplify the expression: M + 5x + 2xy = 6x + 9xy - y
To do this, we can group the terms that contain the same variables together on each side of the equation. First, let's group the terms on the left-hand side:
M + 5x + 2xy = (5x + 2xy) + M
Now, let's group the terms on the right-hand side:
6x + 9xy - y = (9xy - y) + 6x
So the equation becomes:
(5x + 2xy) + M = (9xy - y) + 6x
Next, we can simplify both sides by combining like terms:
5x + 2xy + M = 9xy - y + 6x
Subtracting 5x and 2xy from both sides, we get:
M = 7xy - y + 1x
So the simplified equation is:
M = x(7y + 1) - y
Therefore, M is equal to x times the sum of 7y and 1, minus y.
