w

_ = 6

5
What is the value of w?

multiply both sides by 5 to get rid of the denominator and you get

w(5)/5 = 6( 5)
the 5's cancel out on the left side
and you get left with
w= 30

** always remember - whatever you do to the left side you must do to the right* ( in this case we multiplied left side by 5 so we had to do that to the right side as well)
