Question

35. In each of the following systems of equations (i) determine whether the system has a uníque solution, no solution (or) infinltely many solution, (ü) Find the solution(s) graphically (that is geometrically), if exists. (ii) Verify the solution(s) algebraically.
(a) 2x + y 54x+2y 10
(b) X-2y- 85x-10y 10
(c) 8x +5y 9 3x+2y 4​

Answer 1

easy bro

in equations a1x*2+b1x+c1

a2x*2+b2x+c2

if

a1/a2=b1/b2=c1/c2

then it has infinite roots

if a1/a2=b1/b2is not equal to c1/c2

then it has no solution

if a1/a2 is not equal to b1/b2

then it has unique solution
