\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(2x)/(2)=(19)/(2)}


\bf{Cancel:(2x)/(2)\ because\ that\ gives\ you\ 1}


\bf{Keep:(19)/(2)\ because\ it\ gives\ you\ the\ the\ value\ of\ x}


\boxed{\boxed{\bf{Answer:x=(19)/(2)}}}\checkmark


\bf{Good\ luck\ on\ your\ assignment\ and\ enjoy\ your\ day!}
