#v<=12#

Explanation:

Solve an algebraic inequality in exactly the same way as you would solve an equation, unless you multiply or divide by a negative number. In this case the inequality sign changes around.

#9 >=1/2v +3#

We need to isolate the variable, v. Subtract 3 from both sides.

#9 -3 >=1/2v #

#6 >=1/2v " "larr# multiply both sides by 2

#12 >= v#

This can also be written as: #v <=12#
