Answer:
<h2>The solution is x = 2 and y = 1.</h2>
Step-by-step explanation:
The given equations are x = 4 - 2y.......(1) and 3x - 2y = 4......(2).
Putting the value of the first equation in the second, we get
3x - 2y = 4
or, 3(4 - 2y) - 2y = 4
or, 12 - 6y - 2y = 4
or, 8y = 8
or, y = 1.
Putting the value of y in the first equation, we get x = 4 - 2 = 2.
4/13 is the correct answer because there are 13 different types of cards and 4 of each if the 13 cards. Turning that into a fraction would be 4/13.

Answer:
.....................
10)=(-3)^2.x^4×2.y^2(5.x^2y^6)-7^2x^5×2y^4×2
=(9×5)x^8+2y^2+6-49x^10y^8
=45x^8+2y^2+6-49x^10y^8
=45x^10y^8-49x^10y^8
=-4x^10y^8
