I need an equation with a variable on both sides that equals 4

Answer 1

Let the variable be "x".

Start with:

x = 4 now you can modify the equation by doing the same thing to both sides. Perhaps start with multiplying both sides be 3:

3x = 12 Then add 2x to both sides:

5x = 2x + 12

You can keep going making it more and more complicated as much as you want.
