Prosze o rozwiązanie zadania ale po kolei bo nie zabardzo to rozumiem(5*2x-6)-(4*3x+6)-(10*x-1)=2-1,25x+7
(5*2x-6)-(4*3x+6)-(10*x-1)=2-1,25x+7(10x-6)-(12x+6)-(10x-1)=-1,25x +9Teraz usuwamy nawiasy:10x-6-12x-6-10x+1=-1,25x+9-10,75x=20 /(-10,75)x=-1 i 37/43

(5*2x-6)-(4*3x+6)-(10*x-1)=2-1,25x+7
(10x-6)-(12x+6)-(10x-1)=-1,25x +9
Teraz usuwamy nawiasy:
10x-6-12x-6-10x+1=-1,25x+9
-10,75x=20 /(-10,75)
x=-1 i 37/43
