Sometimes we need to manipulate both equations. We can do this by “criss crossing the coefficients.” 6x + 7y = 11 This is different than Example B, because no coeffcient 5x – 6y = -50 goes into another evenly.-5(6x + 7y = 11) You need the negative sign to ... e4 below deck mediterranean WebThey're going to be plus 0y. Or that whole term is just going to go away. And that's going to be equal to 2.5 plus 25.5 is 28. So you divide both sides. So you get 8x is equal to 28. And you divide both sides by 8, and we get x is equal to 28 over 8, or you divide the numerator and the denominator by 4. That's equal to 7 over 2. That's our x value. Web7x-8y=-11,5x-7y=-13 .
