Question

find the value of k if x = 3 , y= 2 is a solution of the equation 3 X + 4 Y = K find two more solution of the resultant equation

Answer 1

putting the value of x and y

3*3+4*2=k

k=9+8=17           so the value of k is 17

3x+4y=17 is the equation

if x=0 then

0+4y=17

y=17/4                   (0,17/4) is a solution

if x=1 then

3*1+4y=17

y=17-3/4=14/4=7/2       (1,7/2)is a solution

if x=2 then

3*2+4y=17

6+4y=17

4y=17-6=13

y=13/4              (2,13/4) is a solution
