00:03 (iv) Systems of Linear Equations: Solving by Cross-multiplication method; x – 3 y – 7 = 0 ; 3 x – 3 y – 15 = 0

Solve word problems by Cross-multiplication method | Algebra Cross-multiplication method word problems

04:30 Q2. (i) For which values of a and b does the following pair of linear equations have an infinite number of solutions? 2 x + 3 y = 7 ; ( a – b ) x + ( a + b ) y = 3 a + b – 2
11:06 (ii) For which value of k will the following pair of linear equations have no solution?
3 x + y = 1 ; (2 k – 1) x + ( k – 1) y = 2 k + 1
