Answer 1

4x+2(2)=16


4x+4=16
-4 - 4

4x=12
————
4

x=3

Answer 2

3

Explanation:

Isolate the variable, (x). Note the equal sign, what you do to one side, you do to the other.

First, multiply.

4x + 2(2) = 16

4x + 4 = 16

Next, isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS. First, subtract, then divide.

Subtract 4 from both sides.

4x + 4 (-4) = 16 (-4)

4x = `16 - 4

4x = 12

Next, divide 4 from both sides.

(4x)/4 = (12)/4

x = 12/4

x = 3

3 is your answer for x.
