Question

6-5:[4-3:(2-2:x)] = 1.​

Answer 1

Răspuns:

$\bf 6-5:[4-3:(2-2:x)] = 1$

$\bf 6 = 1 + 5:[4-3:(2-2:x)]$

$\bf 6 - 1 = 5:[4-3:(2-2:x)]$

$\bf 5 = 5:[4-3:(2-2:x)]$

$\bf 5 \cdot [4-3:(2-2:x)] = 5$

$\bf 4-3:(2-2:x)= 1$

$\bf 4 = 1 + 3:(2-2:x)$

$\bf 4 - 1 = 3:(2-2:x)$

$\bf 3 =3:(2-2:x)$

$\bf 3 \cdot(2-2:x) = 3$

$\bf 2-2:x = 1$

$\bf 2 = 1 + 2:x$

$\bf 2 - 1 = 2:x$

$\bf 1 = 2:x$

$\red{ \underline{\bf x = 2}}$
