(x+2)(y-2)=(x-9)(y+5)

Step 1

Open the bracket, we get

xy - 2x + 2y -4 = xy +5x - 9y -45

Step 2

Now subtracting xy and 5x on both side in above equation, we get

xy - 2x + 2y - 4 - xy - 5x = -9y - 45

-7x +2y -4 = -9y -45

Step 3

Now adding 9y and 45 on both side in above equation, we get

-...
