Answer:
2x+y=145 and x-y=55.
Explanation:
Let x represent the smaller number and y represent the larger number.
ATQ,
The sum of twice a number and a larger number is 145.
2x+y=145 ...(1)
The difference between the numbers is 55.
x-y=55 ...(2)
Hence, the two equations that represent the situation are 2x+y=145 and x-y=55.
