Justify each step in solving the equation 4x = 7 (x-3) by writing a reason for each statement

Start with parenthesis so that will be 7x - 21so then you will get 4x = 7x - 21 then you will subtract 7x and 4x and you will get - 3x = - 21 and your answer is 7 because both numbers are a negative and that will equal a positive.
