Question

5+2x=-11
6+3x=-54
1+9x=-89
-1-2x=-7
5-4x=-3
1-6x=-11

Answer 1

5+2x=-11
2x = -11-5
2x = -16
=> x = -16/2
=> x = -8

6+3x=-54
3x = -54-6
3x = -60
=> x = -60/3
=> x = -20

1+9x=-89
9x = -89-1
9x = -90
=> x = -90/9
=> x = -10

-1-2x=-7
-2x = -7+1
-2x = 6
=> x = -6/2
=> x = -3

5-4x=-3
-4x = -3-5
-4x = -8 |·(-1)
4x = 8
=> x = 8/4
=> x = 2

1-6x=-11
-6x = -11-1
-6x = -12 |·(-1)
6x = 12
=> x = 12/6
=> x = 2
