Best ResponseYou've already chosen the best response.010(0.3x  0.2y = 4) > 3x  2y = 40 10(0.4x + 0.5y = 1) > 4x + 5y = 10 Use the elimination method to solve for x or y first. 5(3x  2y) = 5(40) > 15x  10y = 200 2(4x + 5y) = 2(20) > 8x + 10y = 40 *Add both equations> 23x = 240 Solve for x. Then plug that x value back into either equations to solve for y. Then, you will get your ordered pair
