Question

the sum of two numbers is 19 their difference is 1

Answer 1

Concept:

• Subtraction, multiplication, and division are the other three basic mathematical operations; addition is one of them.
• Subtraction is a mathematical operation that reflects the removal of things from a collection.

Given:

The sum of the two numbers is 19 and their difference is 1.

To Find:

The two numbers.

Solutions:

In this question, the sum of two questions and their difference is given to us, 19 and 1.

Now, we are asked to find the two numbers.

Let the first number be x and the second be y

So,

$x+y=19\\x-y=1$

Now we will solve the two equations,

$x+y=19+x-y=1\\x+y+x-y=19+1\\2x=20\\x=10$

So, we get x=10.

Now, we will put the value of x=10 in the first equation

$x+y=19\\20+y=19\\y=1$

∴The two required numbers are 10 and 9.
