Question

b) 40+90÷[9+48:(a+6)]=46

dau coroana ​​

Answer 1

Răspuns: $\bf \red{ \underline{a = 2}}$

Explicație pas cu pas:

$\bf 40+90:[9+48:(a+6)]=46$

$\bf 90:[9+48:(a+6)]=46 - 40$

$\bf 90:[9+48:(a+6)]=6$

$\bf 90 = 6 \cdot[9+48:(a+6)]$

$\bf 90 : 6 = [9+48:(a+6)]$

$\bf 15 = [9+48:(a+6)]$

$\bf 15 - 9 = 48:(a+6)$

$\bf 6 = 48:(a+6)$

$\bf 6 \cdot (a+6) = 48$

$\bf (a+6) = 48 : 6$

$\bf (a+6) = 8$

$\bf a = 8 - 6$

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