Set the equations equal to each other because you need to find when they will be the same.

$256 - 3x = 384 - 5x$

$2x = 128$
Divide by 2.

$\bf{Hey\ there!}$

$\bf{7x-4 = 5x+15}$

$\bf{\underline{Subtract}\ 5x\ from\ \ on \ both\ of\ your\ sides!\downarrow}$

$\bf{7x-4-5x=5x+15-5x}$

$\bf{2x-4=15}$

$\bf{\underline{Add}\ by\ 4\ on\ each\ of\ your\ sides!\downarrow}$

$\bf{2x-4+4=15+4}$

$\bf{Cancel:-4+4\ because\ it\ equals\ 0}$

$\bf{Keep:15+4\ because\ it\ helps\ us\ solve\ for\ your\ answer}$

$\bf{15+4=19}$

$\bf{2x=19}$

$\bf{\underline{Divide}\ by\ 2\ on\ your\ sides!\downarrow}$

$\bf\frac{2x}{2}=\frac{19}{2}}$

$\bf{Cancel:\frac{2x}{2}\ because\ that\ gives\ you\ 1}$

$\bf{Keep:\frac{19}{2}\ because\ it\ gives\ you\ the\ the\ value\ of\ x}$

$\boxed{\boxed{\bf{Answer:x=\frac{19}{2}}}}\checkmark$
