Question

solve by cross multiplication method 11x+5y=58,14x-8y=2 ​

Answer 1

Answer:

Step-by-step explanation:

The given polynomials are 11x + 5y = 58 and 14x - 8y = 2

So, by the method of cross multiplication,

11x + 5y - 58 = 0

14x - 8y - 2 = 0

x = {5(-2)-(-8)(-58)} / {11(-8)-14(5)}

  = (-10-464) / (-88-70)

  = -474 / -158

  = 3

y = {(-58)14-11(-2) / {11(-8)-14(5)}

  = -812+22 / -88-70

  = -790 / -158

  = 5

Hence, x = 3 and y = 5
