For X=2-y Look at the following steps.

Step 1. Subtract 2 from both sides


x-2=-y


Step 2. Multiply both sides by -1


-x+2=y


Step 3. Regroup Terms


2-x=y


Step 4. Switch sides


y=2-x


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


Step 2. Divide both sides by 3


x+y= (6)/(3)


Step 3. Simplify

(6)/(3) to
2



x+y=2


Step 4. Subtract
y from both sides.



x=2-y


Done! now lets solve for y.

Step 1. Factor out the common term 3


3(x+y)=6


Step 2. Divide both sides by 3

x+y=
(6)/(3)


Step 3. Simplify
(6)/(3) to
2



x+y=2


Step 4. Subtract
x from both sides



y=2-x


Done!
