Okay, if x-y=11, then y + 11 = x
Now, apply this to the next equation. Since we know y + 11 = x, we can use this instead of x
2(11+y)+y=19
22+2y+y=19
22+3y=19
now make 3y alone
3y=19-22
3y=(-3)
y=-1
Plug y to our first equation to get x
x = 11+-1
x=10
Hope this helps :)

Add these eqn and then you have to cancel out (y) after that add x and 2x which is equal to 3x and also add RHS i.e.30 and divide it by 3

If sum of first 6 digits of AP is 36 and that of the first 16 terms is 255,then find the sum of first ten terms.
Cloud [144]

Answer:

100

Step-by-step explanation:

We have the sum of first n terms of an AP,

Sn = n/2 [2a+(n−1)d]

Given,

36= 6/2 [2a+(6−1)d]

12=2a+5d ---------(1)

256= 16/2 [2a+(16−1)d]

32=2a+15d ---------(2)

Subtracting, (1) from (2)

32−12=2a+15d−(2a+5d)

20=10d ⟹d=2

Substituting for d in (1),

12=2a+5(2)=2(a+5)

6=a+5 ⟹a=1

∴ The sum of first 10 terms of an AP,

S10 = 10/2 [2(1)+(10−1)2]

S10 =5[2+18]

S10 =100

This is the sum of the first 10 terms.

Hope it will help.
