Question

Q3) If x = - 2 and x^2 + 2xy = - 5, then find the value of y. *​

Answer 1

Answer:

putting value in equation

x^2 + 2xy = - 5

4-4y=-5

-4y=-9

y=9/4

Answer 2

Answer:

y= 9/4

Step-by-step explanation:

x² + 2xy= -5

(-2)² + 2(-2)y = -5 (since x= -2)

4-4y=-5

4y= 4+5

4y= 9

therefore, y= 9/4
