Step-by-step explanation:
dx 2+2xy 1 1 2 2
____ = ______ – ___x^2 – ____y^2 – _____x + ______y
dy 3 3 3 3 3
15=3b
15/3 = 3b/b
5= b
Isolate the variable by diving 3 on both sides

Answer:
1/15
Step-by-step explanation:
(1). <em>Multiply both the numerator and denominator of each fraction by the number that makes its denominator equal the LCD (Least Common Denominator). </em>
So lets do step one now, the LCD is 15 so we have to make both denominators agree on one number, so 15 is the number both denominators agree on.
Solve:
2*3/5*3 - 1*5/3*5
(2). <em>Complete the multiplication.</em>
6/15 - 5/15
(3). <em>The two fractions now have like denominators so you can subtract the numerators.</em>
6 - 5 / 15 - 15 = 1/15
*Pro tip:
<em>The denominator doesn't change and stays the same. So you don't </em>
<em>subtract the 15 by 15.</em>
(4). <em>Then you'll get the answer and then if you can simplify then simplify.</em>

The Answer is 1/15, and cannot be simplified.
So the answer is 1/15
Hope this helps!
