Hey there!
If we're solving for the value of "w" then follow these following steps [tex] \frac{2}{5} (w) [/tex] - 40 = ?[tex] \frac{2}{5} [/tex] ← From the looks we have to simplify it[tex] \frac{2}{5} (w) - 40 = ? [/tex] [tex] \frac{40 (5) }{5} [/tex][tex] \frac{2(w) - 200 }{5} [/tex]Take out your like terms if you please! 2(w) - 200 which can also be equivalent to 2(w - 100)[tex] \frac{2(w -100)}{5} [/tex] = ? [tex] \frac{2(w) - 100}{5} [/tex] (5) 2 = ? ; 2 = 0 w - 100 = 0; change the symbol to an addition symbol.. So your problem becomes w + 100 = 0
Therefore, your answer would have to be [tex]w = 100[/tex]
•By the way [tex] \frac{2}{5} [/tex] is changed to 0.4
