Factor out the common term "2".
2(13x+2y) = 54
Now, divide both sides by 2.
13x + 2y = 54/2. <-- <u>We could not divide into a whole number so it's a fraction.</u>
<u />
Simplify 54/2 to 27.
13x + 2y = 27 <--- <u>Since we have a whole number without a letter, we are done with that side.</u>
<u />
Now, we subtract 2y from both sides.
13x = 27 - 2y
Divide both sides by 13.
x = 27 - 2y/13.
<h3>Therefore, we get <u>x = 27 - 2y/13</u></h3>
That would be our final answer.
Good luck on your assignment!

Step-by-Step explanation:
Answer: 1210.1
Step-by-step explanation:
Answer:
No. The method is not fair.
<span>The
probability of pulling a gold or a silver for the first time is 1/10. The
probability of getting the same color the second time is 1/9. The probability
of getting a different color on the second pullout is still 1/10. Therefore,
the chance that same colors will be
pulled out is higher than that of different colors. Betty has an advantage in the drawing by 1.1%.</span>
Solution:
Probability of same color:
1/10+1/9
9/90+10/90
21.1%
Probability of different colors
1/10+1/10
2/10
20%
<span>21.1%-20%=1.1%</span>
