 Question 509031: Solve using the elimination method. Show your work. If the system has no solution or an infinite number of solutions, state this. 4x + 8y = 16 -2x + 5y = 55Answer by mananth(12270)   (Show Source): You can put this solution on YOUR website!4 x + 8 y = 16 .............1 -2 x + 5 y = 55 .............2 Eliminate y multiply (1)by -5 Multiply (2) by 8 -20 x -40 y = -80 -16 x 40 y = 440 Add the two equations -36 x = 360 / -36 x = -10 plug value of x in (1) 4 x + 8 y = 16 -40 + 8 y = 16 8 y = 16 + 40 8 y = 56 y = 7 Solution (-10,7)
