Решите уравнение:
(x+15)×24-8×(4-x)+2×(x-40)=180+20x
Продолжите уравнение:
24-(1/2-x)+(x-y)×(a+в)-2a×(4x+y)=
(x+15)×24-8×(4-x)+2×(x-40)=180+20x
Продолжите уравнение:
24-(1/2-x)+(x-y)×(a+в)-2a×(4x+y)=

24х+360-32 +8х +2х-80 = 180+20х
24х+8х +2х-20х = 180-360+32 +80
14х = -68
х = -68 : 14
х = 4 12/14 = 4 6/7
