We take the first number in the first section, and multiply that against each number in the second section.
2x*2y = 4xy
2x*8=16x
So the beginning part of our equation is 4xy + 16x. Now we need to do the second number in the first section the same way. Remember to bring the subtraction sign!!
Start at the point (2, -3) and then go up 3 and to the right 4 a few points and then go down 3 and to the left 4 a few points and then from there you can get an equation out of it
