Question

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

Answer 1

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.
