Answer:
To solve for x in the equation 9 + 4y = -5x + 7y, we can rearrange the equation to isolate the variable x. Let's move the terms involving x to one side of the equation:
-5x = 9 + 4y - 7y
Next, let's simplify the equation:
-5x = 9 - 3y
Finally, divide both sides of the equation by -5 to solve for x:
x = (9 - 3y) / -5
So, x is equal to (9 - 3y) divided by -5.
