Question

If a - b = 9 and a? + = 881, where a and b are natural mumbers Find a+b​

Answer 1

Answer:

Step-by-step explanation:

a - b = 9        (1)

a + b = 881       (2)

adding equation 1 and 2

a - b = 9

a + b = 881

__________

2a = 890

⇒a = 890/2

⇒a= 445

substituting a = 445 in (1)

we get

455 - b = 9

⇒b = 455-9

⇒b = 446

∴a= 445 and b = 446
