If the values of equation 12-9 (3-x) and 4 (5 / 4x-5) are equal, what is x?

If the values of equation 12-9 (3-x) and 4 (5 / 4x-5) are equal, what is x?

If the values of equation 12-9 (3-x) and 4 (5 / 4x-5) are equal, [5 / 4 times x? = 5x / 4]
Then 12-9 (3-x) = 4 (5x / 4-5)
12-27+9X=5X-20
9X-5X=-20+27-12
4X=-5
X=-5/4.
