Multiply the first equation by -1 to get -4x - y = --5
Then add the second equation 3x + y = 3
+ ____________
-x = -2 or x = 2
then plug in 2 for x in one of the equations and solve for y 4(2) + y = 5
8 + y = 5
Subtract 8 from both sides y = -3
So x = 2, y = -3 or (2,-3)
Answer: 213
Step-by-step explanation: The median is the middle number
in the data set when the data set is written from least to greatest.
So let's start with writing ur data set from least to greatest.
So we have 195, 200, 226, 230.
Notice that there are two middle numbers.
If there are two middle numbers in the data set,
we find the median by taking their average.
In other words, we add the two middle numbers and divide by two.
So we have 200 + 226/2 or 426/2 which is 213.
