Question

if the addition of two. natural numbers is 154 and SUBSTRACTION is 28 so what are the two numbers​

Answer 1

Step-by-step explanation:

Let

x

equal one number and

y

the other number.

One equation would be the sum of the numbers.

x

+

y

=

12

the other equation would be the difference of the two numbers

x

−

y

=

4

Now add the two equations

x

+

y

=

12

and

x

−

y

=

4

(adding

+

y

and

−

y

=

0

)

so

2

x

=

16

Now divide both sides by 2

2

x

2

=

16

2

This gives

x

=

8

Now substitute x into one of the equations and solve for y

8

+

y

=

12

subtract 8 from both sides

8

−

8

+

y

=

12

−

8

This gives

y

=

4

Put values into the second equation to check

8

−

4

=

4

4

=

4

check

x

=

8

and

y

=

4
