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"
[tex]4x=2x+16[/tex]Step 3
solve for x
[tex]\begin{gathered} 4x=2x+16 \\ \text{subtract 2x in both sides} \\ 4x-2x=2x+16-2x \\ 2x=16 \\ \text{divide each side by 2} \\ \frac{2x}{2}=\frac{16}{2} \\ x=8 \end{gathered}[/tex]I hope this helps you
