The correct option is A, which is {(5/7, 12/7)}.
<h2>Given to us,</h2>equation 1, 5x + 2y = 7,
equation 2, y = x+1
To solve the question, as given in equation 2 the value of y which is equal to x+1, Substitute the value of y in equation 1,
Now, we have the value of x, substitute the value in equation 2, to get y,
Taking LCM,
Hence, the correct option is A, which is {(5/7, 12/7)}.
