Answer 1

Answer:

sum of two numbers is 69

first no be x

second no be x +7

x+ x+7 =69

2x=69-7

2x=62

x=62/2

x=31

the first no is 31

and second no is 31+7

=38

Answer 2

Answer:

sum of no.s is 69

let first no. =x and

let second no. =y

let greater no. be x

Step-by-step explanation:

ATQ

x+y = 69 and

x-y = 7

by elimination method

x+y=69

x-y=7

-----------

2x = 69+7

2x= 76

x= 38

therefore ,

x+y =69

38+y=69

y= 69-38

y=31
