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!

If 120% of a is equal to 80% of b, then what is the value of a b in terms of b
SOVA2 [1]
If you would like to know what is the value of a b in terms of b, you can calculate this using the following steps:

120% of a = 80% of b
120/100 * a = 80/100 * b     /*100
120 * a = 80 * b     /120
a = 80 / 120 * b
a = 2/3 * b

The correct result would be a = 2/3 * b.
