(2) diagonal are congruent
4x - 9 = 2x
Solve for x.
4x = 2x + 9
2x = 9
x = 4.5
We can plug 4.5 into the original equation to verify if it's correct.
4x - 9 = 2x
4(4.5) - 9 = 2(4.5)
18 - 9 = 9
The equation is true, and so x = 4.5

difference between x
2 - k
------- = 5
3 - 4
3-4 = -1 so...
-1 ( 2 - k ) = 5
k - 2 = 5
k = 7
