Question

Solve each problem for the given variable
-3c+ac=ac=4 solve for c
X/Y +4=x/5 solve for x

Answer 1

1.
`-3c+ac=4`

2. Factor out C

`c(a-3)=4`

3. Divide both sides by a-3

Answer:
`c= (4)/(a-3)`

1.
`(x)/(y) + 4 = (x)/(5)`

2. Multiply both sides by
`y`

`x+ 4y= (xy)/(5)`

3. Now we need to multiply both sides by 5

`5x+20y=xy`

4. Change xy to a negative because it is a positive and add it to both sides.

`-xy + 5x + 20y= 0`

5. Change 20y to a negative and add it to both sides

`-xy + 5x= -20 y`

6. Now we need to Factor out X

`x(-y+5)=-20y`

7. Divide both sides by
`-y+5`

`(x(-y+5))/(-y+5) = (-20y)/(-y+5)`

Answer:
`x= (-20y)/(-y+5)`
