The values of two numbers are 5, 7
Step by Step Explanation:
Given:
Sum of two numbers is 12 and the differences of two numbers is -2
To find:
Values of the two numbers
Solution;
Since both numbers are unknown, let the first number be x, let the second number be y.
According to question,
Sum of two numbers x+y=12
Difference of two numbers x-y=-2
Adding both the Equations,
[x+y=12]+[x-y=-2]
Solving the above two equations we get
2x=10
x=5
And we know that x+y=12
Substitute the value of x=5 we get
5+y=12
y=12-5=7
y=7
Result:
Thus the value of two numbers are 5 and 7.
