Tommy had $700 saved up, and worked 36 hours this week. James had $70 saved up and worked 43 hours this week. At the end of the week, they had the same amount of money. How much do they make an hour?

700 + 36h = 70 + 43h

       700    = 70 + 7h

       630    = 7h

         90    = h

They make $90 per hour.

Solve for the variable:

2 -(3p - 2) + 5p = -2(5p + 1)

2 -(3p - 2) + 5p = -2(5p + 1)

2 - 3p + 2 + 5p = -10p -2

       4 + 2p       = -10p - 2

        4 + 12p    = -2

             12p     = -6

                p = -1/2
