Write each Equation as a functin in "y=..." form
1. -2(x+3y)=18
Divide both sides by -2 to get:
(x+3y) = -9
3y = -x-9
y = -(x+9)/3
==================
2. 5(x+y)=20+3x
5x+5y= 20+3x
5y = 20-2x
y = (20-2x)/5
--------------------
3.2x-3y=6
3y = 2x-6
y = (2x-6)/3
----------------
4. -10x=5y
y = -2x
=================
