Question

solve this in trail and error method :
$a - 2 = 6$
​

Answer 1

Answer:

a = 8

Step-by-step explanation:

LHS = a-2 RHS = 6

Taking a = 1

1 - 2 = -1

LHS ≠ RHS

Taking a = 2

2 - 2 = 0

LHS ≠ RHS

Taking a = 3

3 - 2 = 1

LHS ≠ RHS

Taking a = 4

4 - 2 = 2

LHS ≠ RHS

Taking a = 5

5 - 2 = 3

LHS ≠ RHS

Taking a = 6

6 - 2 = 4

LHS ≠ RHS

Taking a = 7

7 - 2 = 5

LHS ≠ RHS

Taking a = 8

8 - 2 = 6

LHS = RHS

∴ a = 8
