Решите уравнение: 6x-3,2=7x-3 (2x-2,5)

5 (x-1) + 5 (3x+2) = 6x+8

44-10 (3-4x) = 7 (5x+2)

(x-5) (x+1) - x=x^2+5

(x-1) (x-3) = (x-2) (x-4)

1) 6x-3,2=7x-3 (2x-2,5)

6x-3,2=7x-6x+7.5

5x=7.5+3.2

5x=10.7

x=2,14

5 (x-1) + 5 (3x+2) = 6x+8

5x-5+15x+10=6x+8

14x=3

x=3/14

44-10 (3-4x) = 7 (5x+2)

44-30+40x=35x+14

5x=14+30-44

5x=4

x=0.8

(x-5) (x+1) - x=x^2+5

x²-5x+x-5-x=x²+5

-5x=10

x=-2

(x-1) (x-3) = (x-2) (x-4)

x²-x-3x+3=x²-2x-4x+8

2x=5

x=2,5
