To find y, divide the first equation by 2.
  y = 4

To find x, use that value for y in the second equation. Add 4, then divide by 2.
  15·4 = 2x -4
  60 +4 = 2x
  64/2 = x = 32

The solution is (x, y) = (32, 4).

PLZ!!!! HELP ASAP!!! Problem is in the picture
Strike441 [17]

Step-by-step explanation:

pythagoras theorem: c²=a²+b²

Where c= longest side of a right angle triangle

AB= 6+r = c

AD= 12 =a

CD= r =b

(6+r)² = 12²+ r²

36+12r+r² =144 +r²

12r+r²-r²=144-36

12r=108

r= 108/12

r=9
