Answer:
Volume of 3% alcohol = 80 ml
Volume of 8% alcohol = 120 ml
Step-by-step explanation:
Final volume of 6% alcohol solution = 200 ml
Let the volume of 3% alcohol volume = a ml
Therefore, volume of 8% alcohol = (200 - a) ml
Equation for the given situation will be,
3a + 8(200 - a) = 6×200
3a + 1600 - 8a = 1200
1600 - 5a = 1200
5a = 400
a = 80 ml
Therefore, volume of 3% alcohol to be used = 80 ml
And volume of 8% alcohol to be used = (200 - 80) = 120 ml

Answer:
x=1 y=7
Step-by-step explanation:
−5x+2y=9
y=7x
Substitute the second equation into the first
-5x +2(7x) = 9
Distribute
-5x +14x = 9
Combine like terms
9x=9
Divide by 9
9x/9 =9/9
x= 1
Now find y
y = 7(1)
y = 7
