Question

help so help he out i can know

Answer 1

Here's what we know:

a + b = 19 (the 2 numbers added together is 19)

a - b = 3 (their difference is 3)

We can solve this 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
