To solve for the value of y when x = 0 in the equation xy + 5ey + 5e = 0, we start by substituting x with 0 in the equation.
Substituting gives us:
0*y + 5ey + 5e = 0
Since 0*y is equal to 0, the equation simplifies to:
5ey + 5e = 0
Next, we can factor out 5e:
5e(y + 1) = 0
For this product to equal 0, either 5e must be 0 (which it cannot be, as e is a mathematical constant approximately equal to 2.71828) or:
y + 1 = 0
Solving for y, we subtract 1 from both sides:
y = -1
In conclusion, when x = 0, the value of y in the equation xy + 5ey + 5e is -1.
