Answer: x = 0 or x = 2
Step-by-step explanation:
To solve this, we must note that the two equations speaks of a single function of y. So 
y = 2x - 3 = x² - 3
So from.here we can equate the two together and solve for x. 
 x² - 3 = 2x - 3, biw convert to a quadratic expression
x² - 2x - 3 + 3 = 0
 x² - 2x = 0
Now factorize
 x( x - 2 ) = 0, so solving for x
 x = 0 or x = 2. .I believed getting the 2 won't be a problem 
 When x - 2 = 0
Then x = 2.
