Question

find the value of 'k ' if x=3 ,y=4 is a solution of the equation 2x+3y=k. find one more solution of the resultant equation​

Answer 1

x = 3 , y = 4

2x+3y=k -(i)

Now evaluating the values in (i)

2(3) + 3(4) =k

=> 6 + 12 = k

=> k = 18

So equation is 2x + 3y = 18

Then we can find other zeroes by putting x=0 and y=0 respectively.

Answer 2

2x+3y=k

2(3)+3(4)=k

6+12=k

18=k

The other solution :

Let x=3

2(3)+3y=0

6+3y=0

3y= -6

y= -6/3

y= - 2

(3, - 2)
