Following is the python code that works good for the problem 

tst = int(raw_input())

to_find="machula"

for i in range(tst):

r=raw_input()

t=raw_input()

index=t.find(to_find)

if (index+6)!=(len(t)-1):

t=t[:index] + "12" +t[index+7:]

else:

t=t[:index] + "12"

equal_to=t.find("=")

plus=t.find("+")

s=t.split(" ")

number1=int(s[0])

number2=int(s[2])

number3=int(s[4])

if index<plus:

number1=number3-number2

elif index>equal_to:

number3=number1+number2

else:

number2=number3-number1

print str(number1),"+",str(number2),"=",str(number3)
