First I would bring the -5 in by multiplying the pieces in the brackets.
(-5 x 4= -20, and -5 x 8y = -40y)
This gives us
-20 -40y = 20
add 20 to both sides,
+20 - 20 -40y = 20 + 20
-40y = 40
divide both sides by -40,
-40y/-40 = 40/-40
y = -1

step 1 - open the brackets multiplying the terms inside by -5
step2 - add 20 to both left and right parts of the equation
step 3 - divide left and right by -40 and find y

First you divide both sides by -5. You get
4+8y=-4
Then you subtract 4 from both sides of equation
8y=-8
Last you divide both sdes by 8 and obtain the answer:
y = -1

-5(4+8y)=20 multiply ? factors in the brackets by - 5-20-40y=20-20+20-40y=20+20 add ? both sides of the equation by +20-40y=40-40y/-40=40/-40 divide ? both sides of the equation by - 40y=-1 voila!!

$-5\times\left(4+8y\right)=20$−5×(4+8y)=20
$\frac{\left(-5\times\left(4+8y\right)\right)}{-5}=\frac{20}{-5}$(−5×(4+8y))−5=20−5 (Divide both sides by -5)
$4+8y=-4$4+8y=−4
$4+8y-4=-4-4$4+8y−4=−4−4 (Subtract -4 from both sides)
$8y=-8$8y=−8
$\frac{8y}{8}=-\frac{8}{8}$8y8=−88 (Divide both sides by 8)
