rozwiąż równania :
1) 18 + x = -7
2) 81- x = -13
3) -19 + x = 20
4) 1/2 * ( 20 - 4x ) - 7x = 37

1. 18 + x = -7 / -18
x = -25
2. 81- x = -13 / -81
-x = -94 / *(-1)
x= 94
3) -19 + x = 20 / +19
x= 39
4) 1/2 * ( 20 - 4x ) - 7x = 37
10- 2x - 7x = 37 / -10
-2x - 7x = 27
- 9x = 27 / : (-9)
x= -3
1) 18 + x = -7
x= -7-18
x = -25
2) 81-x=-13
-x=-13-81
-x = -94
x = 94
3)19+x = 20
x=20-19
x=1
4)1/2*(20-4x)-7x= 37
10-2x-7x = 37
-9x=27
x=-3
