Deanna was solving the following equation, 5(x + 2) - 4 = 16.
after her first step the equation looked like this, 5(x + 2) = 20.
what did deanna do to both sides of the equation to begin solving the equation?
add 4 to each side
subtract 4 from each side
multiply both sides by 5
divide both sides by 5
