How do you do the elimination method for 8x-y20 and -5x y-8?
If this is: 8x - y = 20 -5x = y - 8 8x - y = 20 -5x - y = -8 multiply by -1in order to eliminate y; 8x - y = 20 5x + y = 8 add both equations; 13x = 28 x = 28/13 substitute the value of x into the one of the equations in order to find y. For example, substitute it into the first one; 8(28/13) - y = 20 224/13 - y = 20 multiply both sides with 13; 224 - 13y = 260 224 - 224 - 13y = 260 - 224 -13y = 36 multiply both sides by -1; 13 y = -36 divide both sides by 13; y = -36/13 So the solution set is (28/13, -36/13) Check: 8(28/13) -(-36/13)= 224/13 + 36/13 = 260/13 = 20 -5(28/13) = -36/13 - 8 ? -140/13 = -36/13 -8 ? -140/13 = -36/13 - 8(13/13) ? -140/13 = -36/13 - 104/13 ? -140/13 = -140/13
