Given:
<span> x=12, y=8, z=3
4x-yz = 4(12) - (8)(3)
</span>4x-yz = 48 - 24
4x-yz = 24
4y+7x-3y+2x
(7x+2x)+(4y+-3y)
=9x+y
Answer: x * y = 1
Explanation: The only thing that changes between the examples are the first two numbers; the final answer is always 1. This would mean that the first number (x) multiplied by your second number (y) will always answer or equal 1.
