Step-by-step explanation:
triangle MAC=triangle MBD=90 Degree
Therefore, From right angled triangle
AC=BD
The quadrilateral have equal opposite sides, for example:
Then, (4x + 6) must be equal to (7x - 3), and (4y - 3) is equal to (3y + 1), therefore

We can solve that equation for x

Hence, x = 3. Now let's solve the other equation

Then the value of y is 4.
Final answers:
x = 3
y = 4
Answer:
-2x^4y^3 this is right. give me brainliest.
