#x=-8#

Explanation:

Given
#color(white)("XXX")2+10/x=3/4#
(and assuming #x!=0#)

Multiply everything on both sides by #4x# to get rid of the fractions:
#color(white)("XXX")8x+40=3x#

#3x# from both sides
#color(white)("XXX")5x+40=0#

Subtract #40# from both sides
#color(white)("XXX")5x=-40#

Divide both sides by #5#
#color(white)("XXX")x=-8#
