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

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

$v = color(green)(7)$
