a.
Step-by-step explanation:
Answer:
(-
,
)
Step-by-step explanation:
Given the2 equations
6 - 2x = y → (1)
14 + 3x = y → (2)
Substitute y = 14 + 3x into (1)
6 - 2x = 14 + 3x ( subtract 3x from both sides )
6 - 5x = 14 ( subtract 6 from both sides )
- 5x = 8 ( divide both sides by - 5 )
x = - 
Substitute x = -
into either of the 2 equations for the corresponding value of y
Substituting into (1)
y = 6 - 2(-
) =
+
= 
solution is ( -
,
)
Here,
Third term (a) = 5
Seventh term (b) = 9
17th number = ?
Now,
T3 = a + 2d
5 = a + 2d
d = (5 - a)/2 ------ 1.
T7 = a + 6d
9 = a + 6d
d = (9 - a)/6 ------- 2.
Combining eq (1) and (2)
or, (5 - a)/2 = (9 - a)/6
or, 6 (5 - a) = 2 (9 -a)
or, 30 - 6a = 18 - 2a
or, 12 = 4a
◆ a = 3
putting the value of a in eq (1)
or, d = (5 - 3)/2
or, d = 2/2
◆ d = 1
Then,
T17 = a + 16d
= 3 + 16
= 19
◆ T17 = 19
I hope you understand...
This is Right answer...
