Resolver las equaciones: a) \( \frac{3}{2}+\frac{2}{5} x+\frac{1}{10}=-\frac{1}{2} x-\frac{3}{5} \)

\( \left\{\begin{array}{l}\text { Реши систему неравенств: } \\ (5 x+10)-5 \cdot(x+5)>5 x \\ (x-3)(x+8)<0\end{array}\right. \)

48. If \( a=3-\sqrt{2} \) and \( b=\frac{a+1}{a-1} \) what is the value of \( b \)

При каких значениях \( x \) верно, что \( 4 x+8<29 ? \)

100. यदि \( 5^{\sqrt[3]{x}}+12^{\sqrt[3]{x}}=13^{\sqrt[3]{x}} \) है, तो \( x \) का मान है: If \( 5^{\sqrt[3]{x}}+12^{\sqrt[3]{x}}=13^{\sqrt[3]{x}} \), then the value of \( x \) is:

What is the greatest natural number \( x \), so that it leaves remainders 8 and 20 when 308 and 200 are divided by \( \times \) respectively.
