Question

the equation y+1=0 is true only when y is​

Answer 1

y+1=0

y=0-1

y-1

So equation will only be correct if y is -1

Answer 2

SOLUTION

TO DETERMINE

The equation y + 1 = 0 is true only when y is

EVALUATION

Here the given equation is y + 1 = 0

We know that the values of y for which the equation is true is called the roots of the equation

We now find the roots of the equation

y + 1 = 0

⇒ y = - 1

Hence the required value of y = - 1

FINAL ANSWER

The equation y + 1 = 0 is true only when y is - 1
