$=−color(blue)(32w)+ 8x$

$color(blue)(4)(w+2x)+9(−4w)$

$=color(blue)(4) * (w) +color(blue)(4) *(2x)+9(−4w)$

$=color(blue)(4w) + 8x −color(blue)(36w)$

Combining like terms:

$=color(blue)(4w) −color(blue)(36w)+ 8x$

$=−color(blue)(32w)+ 8x$

How do you simplify 4(w + 2x) + 9(-4w)4(w + 2x) + 9(-4w)?
