$\bf[(x+8:2)\cdot3+5] \cdot5=115 \: |</em><em>:</em><em>5\: \text{(\it imprtim toata relatia cu 5)}$

$\bf(x+8:2) \cdot3+5 =23$

$\bf(x+4) \cdot 3 =23 - 5$

$\bf(x+4) \cdot 3 =18 \: \: | </em><em>:</em><em> </em><em>3 \: \text{(\it imprtim toata relatia cu 3)}$

$\bf x+4=6$

$\bf x=6 - 4$

$\boxed{\bf x = 2}$
