2 (x+4) = 16
multiply the bracket by 2
(2) (x) = 2x
(2) (4) = 8
2x+8=16
move 8 to the other side, sign changes from + 8 to - 8
2x+8-8=16-8
2x=16-8
2x=8
divide both sides by 2 to get x by itself
2x/2=8/2
Answer:
x=4

2 (x+4) = 16
---Distribute 2 (x+4)
2x+8=16
--subtract 8 on both sides ... the 8's will cancel out and 16-8=8 ...
2x=8
--Divide 2 on both sides and the 2's will cancel out each other and 8 divided by 2 = 4
Answer: x=4
