Answer :

16 - 12x = 4y

First, divide both sides by 4. / Your problem should look like: [tex] \frac{16-12x}{4} [/tex] = y
Second, factor out the common term 4. / Your problem should look like: [tex] \frac{4(4-3x)}{4} [/tex] = y
Third, cancel 4. / Your problem should look like: 4 - 3x = y
Fourth, switch sides. / Your problem should look like: y = 4 - 3x

Answer: y = 4 - 3x
