Odpowiedź :
a)
[tex]21.25x + 11.5 = 32.75 \\ 21.25x = 21.25 | \div 21.25 \\ x = 1[/tex]
b)
[tex]2.125x + 11.5 = 32.75 \\ 2.125x = 21.25 | \div 2.125 \\ x = 10[/tex]
Odpowiedź:
a) 21,25x + 11,50 = 32,75 / - 11,50
21,25x = 21,25 / : 21,25
x = 1
b) 2,125x + 11,50 = 32,75 / - 11,50
2,125x = 21,25 / : 21,25
x = 10
