Multiply first equaton by 2 and add to the other equation
6x+6y=12
<u>5x-6y=15 +</u>
11x+0y=27
11x=27
divide both sides by 11
x=27/11
sub back
3x+3y=6
divide both sides by 3
x+y=2
(27/11)+y=2
2 and 5/11+y=2
minus 2 and 5/11 both sides
y=-5/11
x=27/11
y=-5/11
(27/11,-5/11)
Answer:
-2

Answer:
.
Step-by-step explanation:
Note: In the given function it should be (n-1) instead of (n=1).
Consider the given function is
It is the explicit form of an A.P.
For 
,
For 
,
Common difference is
The recursive formula of an A.P. is
Substitute 
in the above formula.
Therefore, required recursive formula is .
