1)-3(x-1)=24-10x
2)2(4x+5)-3(x+6)=9x+8

x=3; x=-4

Пошаговое объяснение:

-3(x-1)=24-10x

-3x+3=24-10x

-3x+10x=24-3

7x=21

x=3

2(4x+5)-3(x+6)=9x+8

8x+10-3x-18=9x+8

8x-3x-9x=8-10+18

-4x=16

x=-4

1)-3(x−1)=24−10x

-3x + 3 = 24 - 10x

10x - 3x = 24 - 3

7x = 21

x = 21 : 7

x = 3

2) 2(4x+5) − 3(x+6) = 9x + 8

= 8х + 10 - 3х - 18 = 9х + 8

= 5х - 8 = 9х + 8

= 5х - 9х = 8 + 8

= -4х = 16

+ х = -4
