if 99m + 101n =88, 101m +99n = 122 find the value of m+n

please give me correct answer then I will brainlist your answer if anyone give wrong answer then I will report you ​

Answer 1

★Given:-

99m + 101n = 88

101m + 99n = 122

★To Find:-

Value of m+n

★Solution:-

Adding the equations will give,

101m + 99n =122

+(99m + 101n = 88)

_____________________

200m + 200n = 210

m + n = 210/200 = 21/20

m + n = 21/20

$\boxed{ \sf m+n = \dfrac{21}{20}}$

Hope it helps

Answer 2

Answer:

99m + 101n = 88 ...............(i)

101m + 99n = 122 .............(ii)

Adding (i) and (ii)

101m + 99n = 122

99m + 101n = 88

______________

200m + 200n = 210

Or, m + n = 210/200

Or, m + n = 105/100

Or, m + n = 1.05 Or 21/20

Hence,

m + n = 1.05 or 21/20
