Answer:
7+4+2f-5f+2.
substitute the f.
7+4+2(3)-5(3)+2
Do the multiplication.
7+4+6-15+2.
11+6-15+2
17-15+2
2+2
4.
x=1 y =15
Step-by-step explanation:
hopefully correct
-5x-2y=13 (i)
3x-y=12
-y=12-3x
y=-12+3x (ii)
substitute ii into i
-5x-2(-12+3x)=13
-5x +24-6x=13
-11x=-11
x=1
substitute x into ii
y=-12+3(1)
y=15
.
. . x=1 and y =15
Median = 6.5 or 6 1/2
HOPE THIS HELPED! HAVE A GREAT DAY! :)
