    Question

    If 2x + 3y = 17 and

    2x+2 – 3y+1 = 5, then :
    A x = 1, y = 3 Correct Answer Incorrect Answer
    B x = 3, y = 3 Correct Answer Incorrect Answer
    C x = 3, y = 2 Correct Answer Incorrect Answer
    D x = 1, y = 2 Correct Answer Incorrect Answer

    Solution

    ATQ, Given 2x+3y=17 , 2x+2−3y+1=5 by observation, we can say that at  x=3 y=2 ⇒23+32=17 and 25−33= 32 − 27 = 5 =5 ∴x = 3y = 2
