Answer:
x= 7, y= 16
Step-by-step explanation:
AB= AC (denoted by one vertical line on each side)
y -4= x +5
y= x +5 +4
y= x +9 -----(1)
AD= CD (denoted by 2 vertical lines on each side)
2x +5= x +12
Bring all x terms to one side, constants to the other:
2x -x= 12 -5
x= 7
Substitute x= 7 into (1):
y= 7 +9
y= 16
