To find the value of a Constant from solution
To find the value of a Constant from solution
Following steps can be followed to find the value of the constant term
Illustration: Find the value of k when (3,-5) is the solution of the equation 5x-2y+k=11
Solution: As (-3,-5)is the solution of the linear equation 5x-2y+k=11.Thus it will satisfy this linear equation.
In order to find the value of constant k we have to substitute the value in the equation.
After substitution we get
5(3) - 2(-5) + k = 11
15 + 10 + k = 11
25 + k = 11
k = 11-25 = -14
Illustration: Find the value of k when (0,-7) is the solution of the equation 10x-4y+3k=25
Solution: As (0,-7) is the solution of the linear equation 10x-4y+3k=25.Thus it will satisfy this linear equation.
In order to find the value of constant k we have to substitute the value in the equation.
After substitution we get
divide both sides by 3,we have
k = -1

Students / Parents Reviews [10]
A marvelous experience with Abhyas. I am glad to share that my ward has achieved more than enough at the Ambala ABHYAS centre. Years have passed on and more and more he has gained. May the centre flourish and develop day by day by the grace of God.

10thMy experience with Abhyas is very good. I have learnt many things here like vedic maths and reasoning also. Teachers here first take our doubts and then there are assignments to verify our weak points.
