The first thing that you do when simplifying an expression with the variable’s values known is to distribute the values. EXAMPLE:
3(7x+9)+6(-16x-40); distribute:
21x+27-96x-240; combine like terms:
(21x+(-96x))+(27+(-240))——-> -75x-213; now plug in the values and solve: -75(6)-213=-663

At the start of the month, Stephen’s savings account had a balance of $1,624. He made a $420 withdrawal each week for four weeks
goldenfox [79]
420 x 4 = 1,680. $1,624 - $1,680 = - $56. $600 x 2 = 1,200 + 1000 = 2,200. This minus the $56 he overdrew = an end of month balance of $2,144.
