Question 170027
3x – 6y = 18; solve for y.

This means to isolate y on one side of the equation.

Begin by subtracting 3x from both sides.

This leaves us with -6y = -3x + 18

To solve for y, divide both sides by -6.

y = -3x/-6 + 18/-6

y = (1/3)(x) - 3

We can also write the answer as y = (x/3) - 3

Either way is right.
