Answer:
Both the median and mean are 13
Solving the system we get, x= -1, y= -2 and z= 0
Step-by-step explanation:
Solving the equations to find x, y and z

Adding eq(1) and eq(2)

Adding eq(2) and eq(3)

Multiplying eq(4) by 3 and eq(5) by 2

So, value of z =0
Putting value of z in eq(4)

So, value of x = -1
Now putting value of z=0 and x =-1 in equation 1

So, value of y = -2
So, solving the system we get, x= -1, y= -2 and z= 0

Answer:
x= 6
Step-by-step explanation:
12+3x=30
3x+12=30
3x+12-12=30-12
3x=30-12
3x=18
3x divided by 3 = 18 divided by 3
x=18 over 3
18 divided by 3 is 6
x=6
