1) 4-5x=6-6x
2) 2(4x+5)=7x-1
3) 7x-12=4x+9(2x-3)
4) 47x-7(4x-3)=4(5x-2)
5) 7x-3(3x+5)=1-4(4x-3)
6) 8(x-2)+(3x-3)=11x-19​

Answer 1

Ответ:

1)

$- 5x + 6x = 6 - 4$

$x = 2$

2)

$8x + 10x = 7x - 1$

$8x - 7x = - 1 - 10$

$x = - 11$

3)

$- 15x = - 15$

$x = 1$

4)

$- x = - 29$

$x = 29$

5)

$14x = 28$

$x = 2$
