Answer:

If the question is accurate:
#color(white)("XXX")x=16#

Explanation:

If the equation really is #1/4x=3y=4#
the #(=3y)# is redundant in finding the value of #x#
#color(white)("XXX")1/4x=4#
after multiplying both sides by #4#
#color(white)("XXX")x=16#

If the first equal sign was intended to be a plus (they are on the same key on my keyboard)
#color(white)("XXX")1/4x+3y=4#
subtracting #(3y)# from both sides:
#color(white)("XXX")1/4x=4-3y#
then multiplying both sides by #4#
#color(white)("XXX")x=16-12y#

If the second equal sign was intended to be a plus
#color(white)("XXX")1/4x=3y+4#
multiplying both sides by #4#
#color(white)("XXX")x=12y+16#
