La diferencia de dos numero es 3.su suma es 13 cuáles son los dos numero

The two numbers are 8 and 5

Explanation:

Consider the two numbers as

x

and

y

. From the given data, we write:

x

−

y

=

3

x

+

y

=

13

From the first equation, we determine a value for

x

.

x

−

y

=

3

Add

y

to both sides.

x

=

y

+

3

In the second equation, substitute

x

with

(

y

+

3

)

.

x

+

y

=

13

(

y

+

3

)

+

y

=

13

Open the brackets and simplify.

y

+

3

+

y

=

13

2

y

+

3

=

13

Subtract

3

from each side.

2

y

=

10

Divide both sides by

2

.

y

=

5

In the first equation, substitute

y

with

5

.

x

−

y

=

3

x

−

5

=

3

Add

5

to each side.

x

=

8

step-by-step explanation:

rick has $1400 and sally has $1500

step-by-step explanation:

to find amount of money rick has after 10 years :

principal = $1000 , time = 10 years , rate = 4% annually

to find amount of money sally has after 10 years :

her friend gives to pay her $50 per year, therefore money she has after 10 years = 50 × 10 = $500

also, sally gets $1000 after 10 years,

therefore, total amount of money sally has after 10 years = 500 + 1000 = $1500

so, after 10 years : rick has $1400 and sally has $1500
