#y = -57/8 = -7.125#

Move all the terms with #y# to the right side:

#1/(2y+10) + 4 = -8/(y+5)#

#4 = -8/(y+5) - 1/(2y+10)#

Note that #2y+10 = 2(y+5)#

#4 = -8/(y+5) - 1/(2(y+5))#

Multiply both sides by #y+5# and solve normally.

#4(y+5) = -8 - 1/2#

#4y + 20 = -17/2#

#4y = -57/2#

#y = -57/8 = -7.125#
