Ectton-(b) tviot wnicn two linear systems have exactly the same (unique) solution ? (a) 3x 4y = 2 x - 3y = 1 all of these (b) x+ 2y = 5 2x - 3y = - 4 5x + y = 7

this is a simple Application of solving non homogeneous systems by considering augmented matrix

solutions is a and c option

first method - since it is 2×2 matrix , u can easily find out it's inverse of all three matrix, find A^-1 B , and then check which have same solution. second method - check for sp...

PFA. Ans:A,C
