\begin{gathered} 4x=2x+16 \\ x=8 \end{gathered}

Step-by-step explanation

Step 1

Let

x represents the number

Four times a number=4x

two times that same number=2x

is equal = "="

Step 2

replace

"Four times a number is equal to two times that same number and 16"


4x=2x+16

Step 3

solve for x


\begin{gathered} 4x=2x+16 \\ \text{subtract 2x in both sides} \\ 4x-2x=2x+16-2x \\ 2x=16 \\ \text{divide each side by 2} \\ (2x)/(2)=(16)/(2) \\ x=8 \end{gathered}

I hope this helps you
