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.
