Answer: Infinitely many solutions
Step-by-step explanation:
Let's start solving by using the distributive property and simplifying.
[tex]4(y-2)+4=2(2y-2)\\(4)(y)-(4)(2)+4=(2)(2y)-(2)(2)\\4y-8+4=4y-4\\\\4y+-8+4=4y-4\\4y-4=4y-4[/tex]
As you can see they formed into the same equation. This means that any number can sub in for y giving this infinite solutions.
