Try the others now.

**Reiny**, Tuesday, October 8, 2013 at 1:21pmTo solve any linear equation in x and y for y takes 2 steps

1. move all terms except the y term to the right

-3y = -2x + 9

2. divide each term by the coefficient of the y term

y = (-2/-3)x + 9/-3

y = (2/3)x - 3

Subtract 2x from both sides. Now, you want this in the form of y = mx + b. So, I will write this as -3y = -2x (since you subtract) + 9 (since we know 9 is positive).

-3y = -2x + 9

Now, divide all terms by -3.

y = -2/-3x (or 2/3x like Reiny showed) - 3 (because 9 / -3 = -3)

y = 2/3x - 3

**Can anyone also help me with this question?**, Tuesday, October 8, 2013 at 1:36pmI already know this. I was referring to the other equations.

a (2 + b) = c

Divide both sides by 2+b.

a = c /(2+b)

I'm not sure on the other one.
