Answer::.x=6,y=2
3x - 5y = 8......(1)
X - 5y = - 4......(2)
subtracting equation 2 from 1 we get
Step-by-step explanation:
3x - 5y = 8
X - 5y = - 4
-
------------------
2x=12
x=12/2=6
multiplying equation 2 by3 weget
3x-15y=-12........(3)
subtracting equation 1from 3
3x-15y=-12
3x-5y=8
-
------------------
-10y=-12-8
y=-20/-10=2

Answer: 21
Step-by-step explanation:
Given : Number of red marbles = 4
Number of green marbles =3
Number of transparent marbles =1
Number of yellow marbles =3
Number of orange marbles =3
If we want to count the sets of five marbles are there in which none of them are red or green, the we exclude green and red marbles from the total marbles.
i.e. Total required marbles = 1+3+3=7
Now, the number of possible sets of five marbles are there:-

Hence, the number of possible sets of five marbles =21
