Well if it your basic solve for x.  We perform the order of operations backwards, so instead of PEMDAS we do SadMep. 

So if we have:

4(x+3)-4=12

S-subtraction, we undo that first.  So add 4 to both sides

4(x+3)=16

Next A-ddition, we don't have any outside our parentheses so skip it

D-ivision same as above.

M-ultiplication So we undo the multiplication of 4 on our quantity by dividing both side by 4

(x+3)=4

So now, we can drop our parentheses and we restart our SadMep.

x+3=4

S no, A yes, undo the addition of 3 by subtracting 3 from both sides.

x=1

We have our answer! hope this helps!
