Question

x=-2 and y = 0 is a solution of the equation 4px-3y = 12, then the value of p is (a)-2/3 (b)-3/2 (c) 2 (d) None of the above​

Answer 1

Answer:

(d)None of the above

Answer is p=1/2

Step-by-step explanation:

★ P = 1/2 ★

Given equation , 4px - 3y = 12

By substituting the values of x & y

1.  4 ( p ) ( 3 ) - 3 ( - 2 ) = 12
2. 12p + 6 = 12
3.  6 ( 2p + 1 ) = 12 or 12p = 12 - 6
4.  2p + 1 = 12/6 or 12p = 6
5.  2p = 2 - 1 or p = 6/12
6.  p = 1/2 or p = 1/2

Hence , P = 1/2

Answer 2

Answer:

$4p( - 2) - 3(0) = 12. \\ - 8p - 3 = 12. \\ 8p = 12 + 3. \\ 8p = 15. \\ p = \frac{15}{8} \\ p = 1.875. \\ (d) \: none \: of \: the \: above. \\ brainlest$
