Odpowiedź:
10 – x = 2
-x = 2 - 10
-x = -8 /*(-1)
x = 8
10 : x = 2 /*1x
10 = 2x /:2
x = 5
10 + x = 2 /-10
x = -8
10 · x = 2 / :10
x = [tex]\frac{2}{10} = \frac{1}{5}[/tex]
x – 10 = 2 /+10
x = 12
x : 10 = 2 /*10
x = 20
Odpowiedź:
a) 10 – x = 2 /-10
-x = -8 / *(-1)
x = 8
b) 10 : x = 2 / *x
10 = 2x
x = 5
c) 10 + x = 2 /-10
x = -8
d) 10 · x = 2 / :10
x = [tex]\frac{1}{5}[/tex]
e) x – 10 = 2 / +10
x = 12
f) x : 10 = 2 / *10
x = 20
