Answer: 4 brothers and 3 sisters for a total of 7 siblings
Step-by-step explanation:
Let No. of boys = x
Let No. of girls = y
<u>Each boy has as many brothers as sisters</u>
Hence, (x - 1) = y
Rearranging we get,
x - y = 1 ……….(1)
<u>Now, each girl has twice as many brothers as that of sisters</u>
Hence, 2 * (y - 1) = x
Solving the bracket we get, 2y - 2 = x
Rearranging we get,
-x + 2y = 2 ……….(2)
Adding (1) and (2) using the elimination method, we get
x - y = 1
-x + 2y = 2
<u>y = 3</u>
Substituting value of Y in equation (1),
x - 3 = 1
Solving this we get,
x = 4
Thus, No. of Boys = 4, No. of Girls = 3 and No. of Siblings in the family = 7
Answer:
n=13/7
Step-by-step explanation:
2n+4+6*2=-9*2+8(2n+1)
2n+4+12=-18+16n+8
16+18=16n-2n+8
34=14n+8
34-8=14n
26=14n
n=13/7
