Solve each equation for the specified variable
2) 9wr=81, solve for w
3) 2d-3f=9, solve for f
4) p=(g-9)180, solve for g
5)4x+y-5h=10y+u, solve for x

2) 9wr=81, solve for w
      wr = 9
        w = 9/r

3) 2d-3f=9, solve for f
        -3f = 9 - 2d
           f = (9 - 2d)/ -3
           f = -3 + 2/3(d)

4) P=(g-9)180, solve for g 
    g - 9= P/180
    g = P/180 + 9

5)4x+y-5h=10y+u, solve for x
    4x = 10y + u - y + 5h
    4x = 9y + u + h
      x = (9y + u + h) / 4
