Answer 1

x+4 = 1
x= 1-4
x= -3

x+8=2
x= 2-8
x= -6

x+7= 3
x= 3-7
x= -4

x-5= -3
x= -3 +5
x= 2

x-2=-5
x= -5+2
x= -3

2x= -8
x= -8:2
x= -4

-3x = -15
x= -15:3
x= -5

x:(-5)= 4
x= 4*(+ 5 )
x= 20

x:(-7)=(-3)
x= -3*(+7)
x= -21

20:x = -10
x= -10*(-20)
x=- 200

-18:x= -2
x = -2*(-18)
x= -36

2x-5 = -9
2x= -9+5
2x=-4:(-2)
x= -2

3x+4 =-5
3x= -5-4
3x = -9:(-3)
x= -3

4x-1=-9
4x= -9+1
4x= -8:(-4)
x= -4

7-5x = -13
5x = -13-7
5 x = -20 :(-5)
x= -4

2-9x= -25
9x = -25-2
9x = -29:(-9)
x= -7

6-4x= -22
4x=-22-6
4x= -28:(-4)
x= -7

4x-6 =2x-14
4x-2x = -14 +6
2x= -8
x= -8:(-2)
x= -4

7x+15= 4x-6
7x-4x= -6-15
3x= -21 :(-3)
x= -7

10-2x = 3x-15
-2x-3x = -15-10
-5x= -35
x= -35:5
x= - 7

13-7x= 23-2 x
-7x +2x= 23-13
-5x= 10 :5
x= 2

39-9x= 21-3x
-9x+3x= 21-39
-6x= - 18 :6
x= -3

Scuze la restul nu știu
