Question

Which of the following is a solution to $3x+4y=38?$

• A. (3, 4)
• B. (6, 5)
• C. (2, 19)
• D. (3, 12)

Answer 1

The correct option is B

(6, 5)

The solution of a linear equation satisfies the equation.

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

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

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

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