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
