½x-3y= 1 ⅔
⅓x - ⅔y = -²₉ / +⅔y
½x-3y= 1 ⅔
⅓x= -²₉+⅔y / *3
½x-3y= 1 ⅔
x = -⁶₉ + ⁶₃y
½x-3y= 1 ⅔
x = -²₃ + 2y
½ * (-²₃ + 2y) - 3y = 1 ⅔
x = -²₃ + 2y
-²₆ + y - 3y = 1 ⅔
x = -²₃ + 2y
-²₆ - 2y = 1 ⅔ / +²₆
x = -²₃ + 2y
-2y = 1⁴₆ + ²₆
x = -²₃ + 2y
-2y = 2 / :-2
x = -²₃ + 2y
y=-1
x = -²₃ + 2y
y=-1
x= -²₃ + 2 * (-1)
y=-1
x= -²₃ -2
y=-1
x=-2²₃
Chodziło o to??
Czy o to:
½x-3y= ½ * ¹₃ - 3 * - ½ = ¹₆ +³₂ = ¹₆ + ⁹₆ = ¹⁰₆ = 1⁴₆ = 1²₃
⅓x - ⅔y = ⅓ * ⅓ - ⅔ * (- ½) = ¹₉ +²₆ = ¹₉ + ⅓ = ¹₉ + ³₉ = ⁴₉
