Hope this helps!

Answer 2

given the equation is

`20(2x-8)=440`

to find the value of x

divide 20 both sides

`\begin{gathered} 2x-8=(440)/(20) \\ 2x-8=22 \end{gathered}`

now add 8 both sides

`\begin{gathered} 2x-8+8=22+8 \\ 2x=30 \end{gathered}`

divide by 2 both sides

`\begin{gathered} (2x)/(2)=(30)/(2) \\ x=15 \end{gathered}`
