Solution

The correct option is B 2
In the given equation,

LHS = 5x - 10
RHS= 0

Using $t r i a l a n d e r r o r m e t h o d$ ,

case 1:
putting x = 0,
LHS = $5 \times 0$ - 10 = -10
Hence, LHS is not equal to RHS.

case 2:
putting x = 1,
LHS = $5 \times 1$ - 10 = -5
Hence, LHS is not equal to RHS.

case 3:
putting x = 2,
LHS = $5 \times 2$ - 10 = 0
Hence, LHS is equal to RHS.

case 4:
putting x = 3,
LHS = $5 \times 3$ - 10 = 5
Hence, LHS is not equal to RHS.

$∴$ For x = 2, LHS = RHS.
