Question

of x=k and y=-3/2 is a solution of equation 3x-4y=12 . then find the value of k​

Answer 1

3x – 4y = 12

Given x = k and y = –3/2 is a solution of the equation

3( k ) – ( – 3/2 ) = 12

3k + 3/2 = 12

3k = 12 – 3/2

3k = ( 24 – 3 ) / 2

3k = 21/2

k = 21 / ( 2× 3 )

k = 7/2

Answer 2

Answer:

6

Step-by-step explanation:

3k-4×3/12 = 12

3k-6=12

3K=12+6

3K=18

K=18/3

k=6
