Find the numbers such that twice of the first number added to four times of the second number gives 800 and five times of first number added to the two times the second number gives 720. 2x 4y = 800 .(1). Five times of first number two times the second number = 720. 5x 2y = 720 .(2). Multiply equation (1) by 5 and equation (2) by 2. 5(2x 4y) = 800 * 5. 10x 20y = 4,000 .(3). 2(5x 2y) = 720 * 2. 10x 4y = 1440 .(4). Subtract equation (4) from equation (3). 10x 20y - (10x 4y) = 4000 - 1440. 2x 4 * 160 = 800.
