#x=4#

Explanation:

Given
#color(white)("XXX")9x-8+4x=7x+16#

Collect all terms with #x# factors on the left side and all constant terms on the right
#color(white)("XXX")9x+4xcolor(blue)(-7x)=16color(blue)(+8)#

Simplify
#color(white)("XXX")6x = 24#

Divide both sides by #6#
#color(white)("XXX")x=4#
