Step-by-step explanation:
1. 1/13 2. 1/26
Answer: It is 2.
Step-by-step explanation:
Make both equation equal to each other and solve for x, as following:
- Add like terms.
- Factor the equation.

Substitute the value of x obtained into any of the original equations to obtain the y-coordinate.
Then, this is:

Answer:
y=7
Step-by-step explanation:
We have two numbers,
x
,
y
. We know two things about them:
2
x
+
y
=
25
3
x
−
y
=
20
Let's add these two equations together which will cancel the
y
:
5
x
+
0
y
=
45
x
=
45
5
=
9
We can now substitute in the
x
value into one of the original equations (I'll do both) to get to
y
:
2
x
+
y
=
25
2
(
9
)
+
y
=
25
18
+
y
=
25
y
=
7

x
−
y
=
20

(
9
)
−
y
=
20

−
y
=

Answer:
=
- 4,
= 3
Step-by-step explanation:
A recursive formula allows us to find the next term in the sequence from the previous term.
note the difference between the terms in the sequence
= - 13 - ( - 9) = - 9 - (- 5) = - 5 - (- 1) = - 1 - 3 = - 4
That is to obtain any term in the sequence we subtract 4 from the previous term, hence
=
- 4,
= 3
