Question

determinati cifrele a si b stiind ca ab × r6 -ab ×34-ab =170​

Answer 1

Răspuns:

ab·46-ab·35-ab=170

ab(46-35-1)=170

10ab=170

ab=170:10

ab=17

Answer 2

Răspuns:

$ab \times 46 - ab \times 35 - ab = 170 \\ ab(46 - 35 - 1) = 170 \\ ab(11 - 1) = 170 \\ 10ab = 170 = > ab = \frac{170}{10} = > ab = \color{blue}\large\ 17$
