Answer 1

Answer:

  (x, y) = (18, 9)

Step-by-step explanation:

Assuming the figure is a parallelogram, the diagonals bisect each other. Each half of one diagonal is equal to the other half of that diagonal.

Long diagonal:

  x -3 = 15

  x = 18 . . . . . add 3 to both sides of the equation

Short diagonal:

  y +3 = 12

  y = 9 . . . . . . subtract 3 from both sides of the equation

The variable values are ...

• x = 18
• y = 9

Answer 2

Answer:

x=18, y=9

Step-by-step explanation:

The lines of y+3 and 12 look equal to each other. So do x-3 and 15. Because of this, we set each equal to each other and solve.

solving for x:

x-3 = 15

+ 3     +3

x=18

solving for y:

y+3=12

- 3    -3

y=9
