Let Numbers be x and y respectively.
We have, x+y= 67 . equation .(1)
and x-y= 15 .equation .........(2)
By Adding Eqn. (1) & (2)
x+y= 67
x-y= 15
∴2x= 82
∴x=82/2= 41
By Putting x=41 in eqn. (2)
41-y=15
∴y=26
Answer: The numbers are 12 and −29.
Step-by-step explanation:
We are looking for two numbers. Let n represent the first number, and let m represent the second number. We are given the sum of the two numbers is −17, so that
n+m=−17
We are also given their difference is 41 so that
n−m=41
The system of equations is
n+m=−17
n−m=41
To solve the system, we use elimination. Since the coefficients of m are opposites, we add the equations to eliminate m and solve for n.
n+m=−17
n−m=41
2n=24
n=12
To solve for m, we can substitute n=12 into either of the original equations. Substituting n=12 into the first equation gives
n+m= -17
12+m= -17
m= -29
The numbers are 12 and −29.
