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
