Question

solve plzzzzzzzzz.. .

Answer 1

1(let, the bigger number is x and smaller number is x-1
therefore x+x-1=43
or, 2x= 43+1
or, 2x= 44
or, x= 44/2
or, x =22
therefore bigger number 22, and smaller number is 22-1=21

2) let, her friend age is x
and her age is x-6
therefore x+x-6= 34
or, 2x= 34+6
or, 2x=40.
or, x=40/2
or, x=20
therefore age of the girl is 20-6=14

Answer 2

$\textbf {ANSWER:}$

1. Let the number be = x, x+1

ATQ:

$x + x + 1 = 43 \\ \\ = > 2x = 43 - 1 \\ \\ = > 2x = 42 \\ \\ = > x = 21$
x = 21
x+1 = 22

2.Let the age of the girl be = x

Friend's age = x+6

ATQ:
$x + x + 6 = 34 \\ \\ = > 2x = 34 - 6 \\ \\ = > 2x = 28 \\ \\ = > x = 14$

Girl's age = 14
