$w = 132$

$67 = w - 65$ In the equation, we need to isolate the variable $w$ by joining the constants on the L.H.S. This is achieved by adding $65$ on both sides as shown below: $67 + 65 = w - 65 + 65$ Joining like terms together, we have: $132 = w$ This shows that the equation has a possible solution at the point $w = 132$
