Question

the sum of 2 number is 19 and thier diffrence is 3

Answer 1

Answer:

11 and 8

Step-by-step explanation:

Let the numbers be a and b

ATQ

a + b = 19

a - b = 3

By using the addition method to eliminate a variable:

a + b = 19

a - b = 3

---------

2a + 0b = 22

2a = 22

Divide by 2:

a = 11

11 + b = 19

Subtract 11 from both sides:

b = 8

Check:

11 - 8 = 3

3 = 3
