Answer:
x = 16
I dont quite understand the x = 48 situation? But thats wrong if that's your answe
Explanation:
So you have to find out what x is
in order to do that you have to work out the equation and whatever you do to one side you must do to the other side
simplify 1(x+4) = 20
x + 4 = 20
in order to get rid of 4 on one side you have to subtract it on both sides
so x = 16
