**Answer:**

The value of x is 1 and y = -2

**Step-by-step explanation:**

y = 2x²- 3x - 1;

y = x - 3

2x²- 3x - 1 = x - 3

2x² - 3x - 1 - x + 3 = 0

2x² - 4x + 2 = 0

take 2 as common

2(x² - 2x + 1) = 0

x² - 2x + 1 = 0

x² - x - x + 1 = 0

x(x - 1) - 1(x - 1) = 0

(x - 1) (x - 1) = 0

x - 1 = 0 or x - 1 = 0

**x = 1 or x = 1**

**Now****,**** **

y = x - 3

y = 1 - 3

**y**** ****=**** ****-**** ****2**

**Thus****,**** **The value of x is **1** and y is **-2**
