(Unit: Solving Equations: Variables on Both Sides)

Let Cards with Tom be x

Therefore ,

Cards with Bill=x+28

No. of cards in total=112

x+x+28=112

2x=84

x=42.

Therefore,

Cards with Tom=42

Cards with Tom=42Cards with Bill=70

the x just gets copied along.

the answer is x

x

4.5*x evaluates to 4.5x

multiply 3 and 4.5x

multiply 1 and x

the x just gets copied along.

x

4.5*x*3 evaluates to 13.5x

7/2-4.5*x*3 evaluates to

  + 8 =

the answer is
