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

Answer and Explanation:

Solve each equation for the specified variable :

1) [tex]9wr=81[/tex]

Solve for w,

Divide both side by 9r,

[tex]w=\frac{81}{9r}[/tex]    

[tex]w=\frac{9}{r}[/tex]  

2) [tex]2d-3f=9[/tex]

Solve for f,

[tex]3f=2d-9[/tex]    

[tex]f=\frac{2d-9}{3}[/tex]    

3) [tex]P=(g-9)180[/tex]

Solve for g,

[tex]g-9=\frac{P}{180}[/tex]    

[tex]g=\frac{P}{180}+9[/tex]  

4) [tex]4x+y-5h=10y+u[/tex]

Solve for x,

[tex]4x=10y+u+5h-y[/tex]    

[tex]4x=9y+u+5h[/tex]  

[tex]x=\frac{9y+u+5h}{4}[/tex]
