The expression 7 + 2(x – 3) + 5x is simplified correctly in the correct order. which of the steps has an incorrect justification? step b step c step d step a

  7 + 2(x - 3) + 5x

= 7 +  2x - 6  + 5x     distributed 2 into x - 3

= 7 - 6  +  2x + 5x     grouped like terms together

=    1     +     7x
