#5/6#

This is an equation with constants ( just numbers ) and only 1 unknown (x), so it is solvable.

Collecting all the #x# terms on one side of the equals sign and all the constants on the other side.

With add's or subtract's to move to the other side of the = change the sign giving:

We need the #-3x# and the #-19# to change sides.

#11x+4x+3x=-4+19#

#18x=15#

To get rid of the 18 from #18x# turn it into 1 so that instead of #18xx x# we have #1xx x# which is just #x#

Divide both sides by 18

#18/18xx x=15/18#

#1xx x= (15-:3)/(18-:3) = 5/6#
