Question

the sum of two numbers is 18 and their difference is 6

Answer 1

Answer:

Step-by-step explanation:

x and 18-x are the numbers

x-(18-x)=6

x-18+x=6

2x-18=6

2x=18+6

2x=24

x=12

18-x=6

12 and 6 are the numbers

or,...

x+y=18

x-y=6

add

2x=24

x=12

y=18-12=6

or, because the numbers are so small...

18/2=9

9 and 9 no

10 and 8 no

11 and 7 no

12 and 6 yes

Brainiest answer please .

Answer 2

Answer:

Step-by-step explanation:

Let one number be x

And the other no.be y

where x>y

According to the first given condition,

=>x+y=18 ----------(1)

=>x=18-y

According to the second given condition,

=>x-y=6

Substituting the value of x=18-y

=>18-y-y=6

=>-2y=6-18

=>-2y=-12

=>2y=12

=>y= 6

Now substituting the value of y=6 in equation (1)

=> x+6=18

=> x=12

The two no.s are 12 and 6

Thanks for the question!
