Question

While solving an equation of the form x + m = n (where m and n are constants), Ranjana made a mistake and added m to n instead of subtracting it. By how much would her answer differ from the correct one?

m+n

m-n

n-m

2m​

Answer 1

Answer: n-m is correct

Step-by-step explanation: since, x + m = n or, x = n-m (answer )

Answer 2

Answer:

2m

Step-by-step explanation:

correct answer = n-m

Ranjana's answer = n+m

difference in answer = n + m - (n - m) = n + m - n + m = 2m
