The number of real solution of the system y = and y = 3x - 2 is zero
The system of equations are
y =
y = 3x - 2
Then the equation will be
= 3x - 2
Move 3x - 2 to the left hand side of the equation
- 3x + 2 = 0
Find the value of - 4ac
Here value of a = 3
The value of b = -3
The value of c = 2
Substitute the values in the expression
= - 4×3×2
= 9 - 24
= -15
Here the value of - 4ac is -15
Therefore there is no real valued solution
Hence, the number of real solution of the system y = and y = 3x - 2 is zero
