Question

Solve for x. 4x + 4 = 16

Answer 1

4x + 4 = 16

Subtract 4 from both sides.

4x = 12

Divide 4 off of both sides.

x = 3

Answer 2

The answer is 3 .
x=3
Here's why :
4x+4=16
You get rid of the four by adding -4 . You add -4 to the other side .
4+-4=0
16+-4=12
4x=12
Then you divide by 4 , because you want to find the value of one x.
4x/4=x
12/4=3

x=3

hope it helps !
