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]
