Explicație pas cu pas:

4x + 1 = - 19

4x = - 19 - 1

4x = - 20

x = ( - 20) : 4

x = - 5

___________________

( - 24 ) : ( + 6 ) - ( - 15) × 2 = 26

= - 4 - ( - 30) =

= - 4 + 30 =

= 26

____________________

2x + 5 = - 11

2x = - 11 - 5

2x = - 16

x = ( - 16) : 2

x = - 8

3x + 87 = 0

3x = - 87

x = ( - 87) : 3

x = - 29
