Question

set f
write the missing number to make equation true.
$14 + 6 = \\_\\_\\_\\_\\_ + 12$
both sides are equal.
$14 + 6 = 20$
so, $20 = \\_\\_\\_\\_\\_ + 12$.
the missing number is 8.

Explanation:

Step1: Calculate left-hand side sum

$14 + 6 = 20$

Step2: Isolate the missing number

Let $x$ = missing number. $x = 20 - 12$

Step3: Compute the missing value

$x = 8$

Answer:

8
