Answer 1

$1)6x - 3x = 10 - 7 \\ 3x = 3 \\ x = 3 \div 3 \\ x = 1 \\ 2)5x - x = - 1 - 7 \\ 4x = - 8 \\ x = ( - 8) \div 4 \\ x = - 2 \\ 3)2x + 7 = 6x - 1 \\ 2x - 6x = - 1 - 7 \\ - 4x = - 8 \\ x = ( - 8) \div ( - 4) \\ x = 2 \\ 4)2x - 7 = 4x + 3 \\ 2x - 4x = 3 + 7 \\ 2x = 10 \\ x = 10 \div 2 \\ x = 5 \\5)8x - 5 = 3x - 5 \\ 8x - 3x = - 5 + 5 \\ 5x = 0 \\ x = 0 \div 5 \\ x = 0 \\ 6)5x + 3 = 6x + 1 \\ 5x - 6x = 1 - 3 \\ - x = - 2$

х=2

Answer 2

Пошаговое объяснение:

1028.

1)6х+7=3х+10

3х=3

х=1

2)5х+7=х–1

4х=–8

х=–2

3) 2х+7=6х–1

–4х=–8

х=2

4) 2х–7=4х+3

–2х=10

х=–5

5) 8х–5=3х–5

5х=0

х=0

6) 5х+3=6х+1

–х=–2

х=2

пусть х– задуманное число

(х+5):3=0 |*3

х+5=0

х=–5
