${ \textbf{ \textsf{ \underline{ \underline{✠ Solution}}}}}$

• An equation should be have same sign.
• We may use transposing method to find the value.

${ \textbf{ \textsf{ \underline{ \underline{✠Caculation}}}}} :$

$\to \: 2x - 5 = 15 \\ \to \: 2x = 15 - 5 \\ \to \: 2x = 20 \\ \to \: x = \frac{20}{2} \\ \to \: x = 10$

${ \textbf{ \textsf{ \underline{ \underline{✠Proof }}}}}:$

$2 \times 10 = 20 - 5 = 15$
