You isolate #v# on one side of the equation to get #v=7#.

You can solve this equation by isolating #v# on one side of the equation.

To do that, first add #-3# to both sides of the equation

#color(red)(cancel(color(black)(3))) - color(red)(cancel(color(black)(3))) + 6v = 45 - 3#

#6v = 42#

Now divide both sides of the equation by #6# to get #v# alone on the left side of the equation

#(color(red)(cancel(color(black)(6))) * v)/color(red)(cancel(color(black)(6))) = 42/6#

#v = color(green)(7)#
