1. [tex]-3c+ac=4[/tex] 

2. Factor out C
[tex]c(a-3)=4[/tex]

3. Divide both sides by a-3

Answer: [tex]c= \frac{4}{a-3} [/tex]

1. [tex] \frac{x}{y} + 4 = \frac{x}{5} [/tex]

2. Multiply both sides by [tex]y[/tex]
[tex]x+ 4y= \frac{xy}{5} [/tex]

3. Now we need to multiply both sides by 5 
[tex]5x+20y=xy[/tex]

4. Change xy to a negative because it is a positive and add it to both sides.
[tex]-xy + 5x + 20y= 0[/tex]

5. Change 20y to a negative and add it to both sides 
[tex]-xy + 5x= -20 y[/tex]

6. Now we need to Factor out X
[tex]x(-y+5)=-20y[/tex]

7. Divide both sides by [tex]-y+5[/tex]
[tex] \frac{x(-y+5)}{-y+5} = \frac{-20y}{-y+5} [/tex]

Answer: [tex]x= \frac{-20y}{-y+5} [/tex]
