O 5 - x = 4
- x = 4 - 5
x = 1
Y 4 * x - 7 = 13
4x = 7 + 13
x = 5
M x + 5 = 2
x = 2 - 5
x = - 3
L x : 3 = 3
x = 9
T x * 2 = 6
x = 3
W kolejności: M O T Y L
Odpowiedź:
O = 5 - x = 4
-x = 4 - 5
-x = -1
x = 1
Y = 4 * x - 7 = 13
4x = 13 + 7
4x = 20 /: 4
x = 5
M = x + 5 = 2
x = 2 - 5
x = -3
L = x : 3 = 3
x/3 = 3 /* 3
x = 9
