The value of K if the point (4.K) lies on 4x-3y=7
​

Answer 1

Answer:

4x-3y=7.

(or).

4x-3y-7=0.

x=4 & y=k.

4(4)-3(k)-7=0. (or). 4(4)-3(k)=7.

16-3k-7=0. (or). 16-3k=7.

9-3k=0. (or). -3k=7-16.

3k=9. (or). -3k=-9.

(or). 3k=9.

k=9/3. (or). k=9/3.

k=3. (or). k=3.

4(4)-3(3)-7=0. (or). 4(4)-3(3)=7.

16-9-7=0. (or). 16-9=7.

7-7=0. (or). 7=7.

0=0.

I think this is your answer.
