Solve for x and y 1.5x + 0.1y =6.2 and 3x - 0.4y=11.2
Answer»
Given 1.5x + 0.1y = 6.2 3x - 0.4y = 11.2 Multiplying 2 in EQN 1 3x + 0.2y = 12.4 3x - 0.4y = 11.2 Subtracting both we get 0.6y = 1.2 => y = 1.2/0.6 = 2 and putting y in eqn 1 we get 1.5x = 6.2 - 0.2 1.5x = 6 => X = 4 So solution of your question is x = 4 and y = 2
