Solve the following systems of equation using cross multiplication method.
0.5x + 0.8y = 0.44, 0.8x + 0.6y = 0.5
The given equations are
0.5x + 0.8y – 0.44 = 0
0.8x +0.6y – 0.5 = 0
For cross multiplication method, we write the coefficients as
Hence, we get 
= 
= 
⇒ 
= 
= 
⇒ 
= 
= 
⇒ x = 
= 0.4
⇒ y = 
= 0.3
∴ (0.4, 0.3) is the solution to the given system.
