find the Bezout coefficients and write the gcd (243, 715) a s a linear combination of 243 and 715.

Let u = -7 5 -6 , V = -7 7 equation 5-2 -6 6 7 -2 6 X₁ x2 X₁ X2 (Simplify your answers.) and w= - 14 -11 - 12 - 14 - 11 . It can be shown that -5u-7v-w=0. Use this fact (and no row operations) to find x₁ and x₂ that satisfy the - 12
