Frankie Cordova · Answer 1

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

Hadassah Duarte · Answer 2

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
