Question

solve 9+x=14 by trail and error method​

Answer 1

Answer:

X = 5

Step-by-step explanation:

Solution :

Method 1

$\sf \implies9 + x = 14$

$\sf \implies \: x = 14 - 9$

$\sf \implies \: x = 5$

Method 2

If we consider x = 0

Then,

9 + 0 = 14

$9 \not=14$

Put, x = 1

9 + 1 = 14

$10 \not = 14$

Similarly check for x = 2,3,4,5,6

So, for x = 5

we get,

9 + 5 = 14

14 = 14

Hence, x = 5
