Answer:

Step-by-step explanation:

Answer:

The two numbers are  

4

and  

6

.

Explanation:

Let one number be represented as  

x

and the other as  

y

.

According to the problem:

x

=

2

3

y

and  

x

+

y

=

10

From the second equation we get:

x

+

y

=

10

y

=

10

x

(subtracting  

x

from both sides)

Replacing the value of  

y

in the first equation we get:

x

=

2

3

y

x

=

2

3

(

10

x

)

Multiplying both sides by  

3

we get:

3

x

=

2

(

10

x

)

Opening the brackets and simplifying we get:

3

x

=

20

2

x

Add  

2

x

to both sides.

5

x

=

20

Divide both sides by  

5

.

x

=

4

Since from the second equation we have:

x

+

y

=

10

substituting  

x

with  

4

we get:

4

+

y

=

10

Subtract  

4

from both sides.

y

=

6
