#x=65^@,y=62^@#

Explanation:

#"we can write the following equations from the statements"#

#x+y=127to(1)#

#x=1/2y+34to(2)#

#"substitute " (2)" into " (1)#

#rArr1/2y+34+y=127#

#rArr3/2y+34=127#

#"subtract 34 from both sides"#

#3/2ycancel(+34)cancel(-34)=127-34#

#rArr3/2y=93#

#rArry=93/(3/2)=93xx2/3=62#

#"substitute this value into " (1)" and solve for x"#

#x+62=127rArrx=65#

#rArrx=65^@" and " y=62^@#

#color(blue)"As a check " 62+65=127#

#x=65,y=62#

Explanation:

Let the measure of angle x be #x# and angle y be #y#.

We are given two pieces of information:
#x+y=127# .........(1)
#x=y/2+34# .........(2)

Substituting (2) into (1) gives
#y/2+34+y=127#
#y=62#

Substituting #y=62# into (1) gives
#x+62=127#
#x=65#

Therefore #x=65,y=62#
