For X=2-y Look at the following steps.
Step 1. Subtract 2 from both sides
![x-2=-y](/tpl/images/0461/8162/3b705.png)
Step 2. Multiply both sides by -1
![-x+2=y](/tpl/images/0461/8162/04ec7.png)
Step 3. Regroup Terms
![2-x=y](/tpl/images/0461/8162/eae7e.png)
Step 4. Switch sides
![y=2-x](/tpl/images/0461/8162/6592a.png)
Done! :)
For 3x+3y=6 look at the following steps.
To solve for X look at the following steps.
Step 1. Factor out the common term 3
![3(x+y)=6](/tpl/images/0461/8162/8e131.png)
Step 2. Divide both sides by 3
![x+y= \frac{6}{3}](/tpl/images/0461/8162/a9335.png)
Step 3. Simplify
![\frac{6}{3}](/tpl/images/0461/8162/4a68a.png)
to
![2](/tpl/images/0461/8162/05229.png)
![x+y=2](/tpl/images/0461/8162/3f578.png)
Step 4. Subtract
![y](/tpl/images/0461/8162/9512c.png)
from both sides.
![x=2-y](/tpl/images/0461/8162/0a13e.png)
Done! now lets solve for y.
Step 1. Factor out the common term 3
![3(x+y)=6](/tpl/images/0461/8162/8e131.png)
Step 2. Divide both sides by 3
x+y=
![\frac{6}{3}](/tpl/images/0461/8162/a6483.png)
Step 3. Simplify
![\frac{6}{3}](/tpl/images/0461/8162/4a68a.png)
to
![2](/tpl/images/0461/8162/05229.png)
![x+y=2](/tpl/images/0461/8162/3f578.png)
Step 4. Subtract
![x](/tpl/images/0461/8162/a0e3f.png)
from both sides
![y=2-x](/tpl/images/0461/8162/6592a.png)
Done!
