X × 2,5 + 7,5 = 36,5
X × 2,5 = 36,5 - 7,5
X × 2,5 = 29
X = 29 : 2,5
X = 11,6

\(x+1538=3215\\ \Rightarrow x=3215-1538=1677\\ x-215=1578\\ \Rightarrow x=1578+215=1793\\ 345-x=182\\ \Rightarrow x=345-182=163\)

\(\Leftrightarrow\left(x+2\right)^3=343\)
=>x+2=7
hay x=5
\(7+\frac{2}{9}.x=-\frac{1}{9}\)
\(\frac{2}{9}.x=-\frac{1}{9}-7\)
\(\frac{2}{9}.x=-\frac{64}{9}\)
\(x=-\frac{64}{9}:\frac{2}{9}\)
\(x=-32\)
