Question

12-[x-300:(83+1139:67)]:27=1 va rog repedeeee urgent​

Answer 1

Răspuns: $\bf \red{ \underline{x = 100}}$

Explicație pas cu pas:

Folosim metoda mersului invers pentru a rezolva exercițiul

$\bf 12- \big[x-300: \big(83+1139:67 \big) \big]:27=1$

$\bf 12 = 1 + \big[x-300: \big(83+1139:67 \big) \big]:27$

$\bf 12 - 1 = \big[x-300: \big(83+1139:67 \big) \big]:27$

$\bf 11 = \big[x-300: \big(83+1139:67 \big) \big]:27 \: \: \: \: \: \: \: \bigg | \cdot27$

$\bf 297 = x-300: \big(83+17 \big)$

$\bf 297 + 300: \big(83+17 \big) = x$

$\bf 297 + 300: 100 = x$

$\bf 297 + 3= x$

$\bf \red{ \underline{x = 100}}$
