Divide the composite shape into 2 rectangles.

The dimensions of the 2 rectangles are :

w * (x + z)
y * z

Then, we plug in the values.

1st Rectangle

7 * (14 + 10)

7 * 24

168

2nd Rectangle

9 * 10

Find inverse of x+a

x+a=y

interchAnge

y+a=x
y=x-a

Inverse is

f^{-1}x=x-a

Now

x-a=cx-d
x-cx=a-d
x(1-c)=a-d
x=a-d/1-c

You can have any number according to this but

c must not be 1
a and d must not be equal .
All three should belongs to integers set

Note:-

As there is no b given in question (May be missed in typing) Part-2 's equation can't be executed and part 3 also
