3. how many solutions does the system have? }
sy = x2 + 4x – 2
1 y = 2x+1

Hence two solution of expression

I.e x= 1 , - 3

Step-by-step explanation:

Given as :

y = x² + 4 x - 2

And y = 2 x + 1

Solving these equation

x² + 4 x - 2 = 2 x + 1

or, x² + 4 x - 2  - 2 x -  1 = 0

Or, x² + 2 x - 3 = 0

Or,  x² + 3 x - x - 3 = 0

Or, x ( x + 3 ) -1 ( x + 3 )= 0

Or, ( x + 3 ) ( x - 1 ) = 0

or, x = - 3  And x = 1

Hence two solution of expression Answer

x =±sqrt(1/3)

step-by-step explanation:

x+4/6x=1/x

multiply each side by 6x to get rid of the fractions

6x*(x+4/6x)=1/x*6x

distribute

6x^2 +4 = 6

subtract 4 from each side

6x^2 +4-4 = 6-4

6x^2 =2

divide by 6

6x^2/6 = 2/6

x^2 = 1/3

take the square root of each side

sqrt(x^2) = ±sqrt(1/3)

x =±sqrt(1/3)

answer: you need to organize this better it does not make sense.
