solve for w. w - 86 = -42 w = \\boxed{}

$solve for w. w - 86 = -42 w = \\boxed{}$

solve for w.
w - 86 = -42
w = \boxed{}

To isolate $ w $, we add 86 to both sides of the equation $ w - 86 = -42 $. This gives $ w - 86 + 86 = -42 + 86 $.

Simplifying the left side, $ -86 + 86 = 0 $, so we have $ w = -42 + 86 $. Calculating the right side, $ -42 + 86 = 44 $.

$ 44 $
