#x = 400" " 34/100 xx 400 = 136#

Write an equation which says in maths exactly what you have asked in English.

#34% "of " x = 136#

#34/100 xx x = 136#

Now isolate #x# by multiplying both sides by #100/34#

#color(red)(100/34) xx 34/100 xx x = 136xx color(red)(100/34)#

#cancel100/cancel34 xx cancel34/cancel100 xx x = 136xx 100/34#

#x = 400#
