Solve 7x-4 = 5x+15 for x

tatiyna

$\bf{Hey\ there!}$

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

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

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

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

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

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

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

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

$\bf{15+4=19}$

$\bf{2x=19}$

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

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

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

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

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

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

10ft 19 ft how do you do this

tino4ka555 [31]

If we're talking about a box with dimensions 10 ft, 19 ft and 20 ft, it's probable that the instructions say to calculate the volume. That would be

V = (10 ft)(19 ft)(20 ft) = 3800 cubic feet.
