Question

En la ecuación x2+3=2x+y
, si x=−4
, ¿cuál es el valor de y
?

Answer 1

• The value of y is 11.

Given equation:

x² + 3 = 2x + y

If x= - 4

Simply put the value of x = -4 in the given equation,

Further solving for value of y,

• x² + 3 = 2x + y
• (-4)² + 3 = 2(4) + y
• 16 + 3 = 8 + y
• 19 = 8 + y
• 19 - 8 = y
• 11 = y

Verification:

• x² + 3 = 2x + y

Substitute x as -4 and y as 11 in the above equation,

• (-4)² + 3 = 2(4) + 11
• 16 + 3 = 8 + 11
• 19 = 19

Hence our answer is verified.

So The required value of y is 11.
