Chapter=32x-3y=7(a+b) x-(a+b-3) y=4a+b |
| Answer» Value of a, b = -5, -1 derived from the system of linear equation given which has infinite number of solution.Solution:For an equation to have infinite solution, the equations should be same as for now let us equate the equations and then solve it2x - 3y=7 (a+b)x-(a+b-3)y = 4a+bEquate the value of ax + by = cn in both cases, after this we get:a+b=2na+b-3=-3n and 4a+b=7n. Solving these we get the value of n = -3.Putting the value of n, we get a+b=-6a+b-3=18 4a+b=-21Solving the above equation, we get:a=-6-b-4(6+b)+b=-21b= -1 Putting the value of b in a = -6-ba = -5.Therefore, the value of a & b = -5, -1 | |
