Answer:

$4(x - 2) = 2(2x + 6)$

open brackets [ distributive property ]

$4x - 8 = 4x + 12$

collect like terms together:

$4x - 4x = 12 + 8 \\ 0x = 20$

${ \boxed{ \boxed{ \bf{ \red{no \: \: solution}}}}}$

\end{cases}$

she should have invested P, in order to get I = 6500

but she instead invested 17,801, how much more did she need? well, P - 17801
