Question 664881: Write the equation in function form, solve for y
9y + 18 =3x
-x + 3 = 0
Solve each equation or formula for the variable indicated
d=rt, for r
ab + 3c = 2x, for b
rx + 9/5 = h, for x

Answer by vleith(2983) (Show Source): You can put this solution on YOUR website!
You are being asked to find equations for a given variable in terms of all the other variables. Basically, you need to 'get the given variable' on one side of an equation and everything else on the other side.
solve for y

So that is an equation for y.
You are also told -x + 3 = 0. So that says x = 3.
Given x = 3, use the equation for y to solve for y

Now lets do another one
This is a common equation. Distance = rate*time. You need to know this one
You are asked to solve that equation for r

Next one
solve for b

You get the idea. You do the last one
