#x=-1 7/8 or -1.875#

#(5x)/3+9/8=(7x)/6+3/16#

#:.(80x+54=56x+9)/48#

#:.(80x)/48+54/48=(56x)/48+9/48#

#:.80x+54=56x+9#

#:.80x-56x=9-54#

#:.24x=-45#

divide both sides by 3

#:.8x=-15#

#:.x=-15/8#

#:.x=-1 7/8or -1.875 #

check:

substitute #x= -1.875#

#:.5(-1.875/3)+1.125=7(-1.875)/6+0.1875#

#:.5(-0.625)+1.125=-2.1875+0.1875#

#:.-3.125+1.125=-2.1875+0.1875#

#:.-2=-2#
