Question

28.If x=3 and y=-2 is a solution of the equation 4px-
3y=12, then the value of p is: *
a) 0
b)1/2
c)2
d)3​

Answer 1

Given :  x = 3 and y = -2 is a solution of the equation 4px - 3y = 12,

To Find :  value of p

Solution:

Solution of the equation satisfy the equation.

equation 4px - 3y = 12,

x = 3 and y = -2 is a solution

Hence Substitute x = 3 and y = - 2

=> 4p(3) - 3(-2)  = 12

=> 12p + 6 = 12

=> 12p = 12 - 6

=> 12p = 6

=> p = 6/12

=> p = 1/2

Value of p  is  1/2

Correct option is b)  1/2
