Answer:
Option A: x+y=136 and x-y=34 is the correct answer.
Step-by-step explanation:
Let,
x and y be the two numbers.
According to given statement,
The sum of two numbers is 136.
x + y = 136 Eqn 1
The difference of two numbers is 34.
x - y = 34 Eqn 2
x+y=136 and x-y=34 is the system of equations that could be used to solve and determine the numbers.
Hence,
Option A: x+y=136 and x-y=34 is the correct answer.
