Will give first answer brainliest use the substitution method to solve the system of equations. 3x + 7y = 1 y = x – 7 a. (3, –4) b. (4, –3) c. (2, –5) d. (5, –2)

The correct option is (D) (5, -2).

Step-by-step explanation:  We are given to use the method of substitution to solve the following system of equations :

Substituting the value of y from equation (ii) in equation (i), we get

and from equation (ii) again, we get

Thus, the required solution is (x, y) = (5, -2).

Option (D) is CORRECT.
