Answer:
x=-1 y =-1
Step-by-step explanation:
multiply equation 1 with (-2)
+6x-2y=-14
5x+2y=3
now add equation 1 to equation 2
11x=-11
x=-1
now substitute x=1 in 1 or 2
5(1)+2y=3 5+2y=3 2y=3-5 2y= -2 y= -1
The median is the moddle number of a data set. If the number of numbers is even add the 2 middle numbers and divide by 2.
Median = (7+7)÷2 = 7
The mean is the averagw value in a data set. You find it be adding all the numbers and then divide the answer by the number of numbers.
