Question

What is the solution to X=2-y 3x+3y=6

Answer 1

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

$x+y= \frac{6}{3}$

Step 3. Simplify $\frac{6}{3}$ 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=$\frac{6}{3}$

Step 3. Simplify $\frac{6}{3}$ to $2$

$x+y=2$

Step 4. Subtract $x$ from both sides

$y=2-x$

Done!
