Question

Solve for y: 3x – 6y = 9

Answer 1

Hallo! :D

In the last problem you asked and I answered, it had said that if we had a math problem with two variables, and we only solve for one, the other will end up in our answer.

Step 1) Add -3x to both sides.

$3x + 6y + -3x = 9 + - 3x 6y = -3x + 9$

Step 2) Divide both sides by 6.

$\frac{6y}{6} = \frac{-3x + 9}{6}$

$Y = \frac{-1}{2} x + \frac{3}{2}$

Final Answer -

$Y = \frac{-1}{2} x + \frac{3}{2}$

Hope this helps! :D
