Since we have a unique value of x and y, it shows that the system of the equation is consistent and independent.
Given the system of equation expressed as:
3x + y = 3
x - 2y = 4
Solve simultaneosly;
3x + y = 3 ............. 1 * 1
x - 2y = 4 ...............2 * 3
_________________________
3x + y = 3
3x - 6y = 12
Subtract
y-(6y) = 3 - 12
7y = -9
y = -9/7
Substitute y = -9/7 into the equation to get x
x - 2y = 4
x - 2(-9/7) = 4
x + 18/7 = 4
x = 4 - 18/7
x = 3/7
Since we have a unique value of x and y, it shows that the system of the equation is consistent and independent.

Answer:
The median is 10 and the mean is 10.2
Step-by-step explanation:
Median: the middle number -> 6,8,10,11,16
Mean:
6 + 8 + 10 + 11 + 16 = 51
51/5 = 10.2
Let A be the amount of 100% acid.
100A+20*(6)=40*(A+6)
100A+120=40A+240
60A=120
A=2 gallons
Point form(-4,-2) or equation form x=-4,y=-2
