Solution

The correct option is B
(6, 5)

The solution of a linear equation satisfies the equation.

$3 \times 3 + 4 \times 4 = 9 + 16 = 25 \neq 38 \to$ (3, 4) does not satisfy the equation.

$3 \times 6 + 4 \times 5 = 18 + 20 = 38 \to$ (6, 5) satisfies the equation.

$3 \times 2 + 4 \times 19 = 6 + 76 = 82 \neq 38 \to$ (2, 19) does not satisfy the equation.

$3 \times 3 + 4 \times 12 = 9 + 48 = 57 \neq 38 \to$ (3, 12) does not satisfy the equation.
