Question

How do you do 2(x+4)=16

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

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
