Answer:
The solution set is (6,3)
Step-by-step explanation:
Begin by multiplying equation 1 by 2. You'll see why in a moment
2y = 2*(1/2) x
2y = x
Substitute this value into equation 2.
2y + 4y = 18 Combine like terms on the left
6y = 18 Divide both sides by 6
6y/6 = 18/6 Do the division
y = 3
To solve for x just use the top equation
y = 1/2x
3 = 1/2x Multiply by 2
3*2 = x
x = 6

Answer:
17:7
Step-by-step explanation:
The first jar is 2/3 water, and the second jar is 3/4 water. Since the jars are equal volume, the resulting mixture will be the average.
(2/3 + 3/4) / 2
(8/12 + 9/12) / 2
(17/12) / 2
17/24
If the jar is divided into 24 parts, 17 parts are water, and the remaining 7 parts are vinegar. So the ratio is 17:7.
