%282w%2B2%29%2F10=+4w%2F18 Start with the given equation.


18%282w%2B2%29=+10%284w%29 Cross multiply


18%282w%2B2%29=+40w Multiply


36w%2B36=40w Distribute.


36w=40w-36 Subtract 36 from both sides.


36w-40w=-36 Subtract 40w from both sides.


-4w=-36 Combine like terms on the left side.


w=%28-36%29%2F%28-4%29 Divide both sides by -4 to isolate w.


w=9 Reduce.
