Cross multiplication is only applicable when we have a pair of linear equations in two variables Let us suppose that a1x b1y c1 = 0 and a2x b2x c2 = 0 are the two equations which has to be solved By using cross multiplication, we will get the values x and y such as x = b1 c2 − b2 c1 b2 a1 − b1 a2 x = b 1 c 2 − b 2 c 1 b 2 a 1 Ex 21, 1 If (x/3 " 1, y –" 2/3) = (5/3 "," 1/3) , find the values of x and y (x/3 " 1, y –" 2/3) = (5/3 "," 1/3) Since the ordered pairs are equal, corresponding elements are equal Hence x/3 1 = 5/3 x/3 = 5/3 – 1 x/3 = 2/3 x = 2 y – 2/3 = 1/3Subtract x^ {3} from both sides Subtract x 3 from both sides Combine x^ {3} and x^ {3} to get 0 Combine x 3 and − x 3 to get 0 Reorder the terms Reorder the terms This is true for any x This is true for any x Use the distributive property to multiply xy by x^
