Answer: The numbers are 14 and 5.
Step-by-step explanation:
Let the numbers are x and y .
According to the given question , we have the following system of linear equation:
[tex]x+y=19-----------------(1)\\\\ x-y=9------------(2)[/tex]
Adding equation (1) and (2) , we get
[tex]2x=28[/tex]
Divide both sides by 2 , we get
[tex]x=14[/tex]
Subtract equation (2) from (1) , we get
[tex]2y=10[/tex]
Divide both sides by 2 , we get
[tex]y=5[/tex]
Therefore , the numbers are 14 and 5.
The first number is 14 and the second number is 5 if the sum of the two numbers is 19 and their difference is 9.
What is a linear equation?
It is defined as the relation between two variables if we plot the graph of the linear equation we will get a straight line.
If in the linear equation one variable is present then the equation is known as the linear equation in one variable.
Let's suppose the first number is x and the second number is y:
According to the question, we can draw two linear equations:
x + y = 19 ....(1)
x - y = 9 .....(2)
Adding equations first and second, we get:
2x = 19+9
2x = 28
x = 14
Put this value in the equation first, we get:
14 + y = 19
y = 5
Thus, the first number is 14 and the second number is 5 if the sum of the two numbers is 19 and their difference is 9.
