Solve the following system of equations using cross multiplication method

(i) 3 x + 4 y = 24, 20 x - 11 y = 47 Solution

(ii) 0.5 x + 0.8 y = 0.44 , 0.8 x + 0.6 y = 0.5 Solution

(iii) (3x/2) - (5y/3) = -2 , (x/3) + (y/2) = 13/6 Solution

(iv) (5/x) - (4/y) = -2 , (2/x) + (3/y) = 13 Solution

Formulate the following problems as a pair of equations and find their solutions :

1. One number is greater than thrice the other number by 2. If four times the smaller number exceeds the greater by 5, find the numbers.

Solution
