Răspuns:
x = -49/60; y = -1/15
Explicație pas cu pas:
3x+2y-1/6 + x-y-³⁾5/2 = -6
x -3y+³⁾1/4 -2x-y-⁴⁾1/3 = 1 <=>
4x+y - 16/6 = -6 <=>
³⁾4x+³⁾y - 8/3 = ³⁾-6
¹²⁾-x-¹²⁾4y -1/12 = ¹²⁾1 =>
12x+3y-8 = -18
-12x-48y-1= 12 <=>
12x+3y = -18+8 = -10
-12x-48y = 13
___________
-45y = 13-10 = 3 => y =3/(-45) => y = -1/15
12x +3·(-1/15) = -10 <=> 12x- 1/5 = -10 => ⁵⁾12x = -⁵⁾10+1/5 =>
60x = -49 => x = -49/60
