Your equation will become

#30a - 5b - 15b +20a# when you get rid of parantheses

#=30a + 20 a - 5b - 15b#

#=50a - 20 b#

#=10(5a-2b)#

#50a - 20 b #

#5 (6a - b) - 5( 3b - 4a)#

Open the brackets
# 5# x#6a - 5# x # b - 5 # x #3b -5# x#-4a#

# 30 a - 5b - 15 b + 20a #

group terms with same variables
# 30a + 20 a -5b -15 b #

Solving, we get
#50a - 20 b #
