$( { \frac{3}{7}) }^{ - 2x + 1} \div { \frac{3}{7} }^{ - 1} = \{( { { \frac{3}{7} )}^{ - 1} \}}^{ - 7} \\ \\ { \frac{3}{7} }^{ - 2x + 1 + 1} = ( \frac{3}{7} )^{7} \\ \\ { \frac{3}{7} }^{2x + 2} = { \frac{3}{7} }^{7} \\ \\ 2x + 2 = 7 \\ \\ 2x = 5 \\ \\ \large \boxed{\boxed{ \bf \orange{ x = \frac{5}{2} }}}$
