Question

check weather the condition is satisfied
1. x+3=0 for x=-3,9,10​

Answer 1

If x = -3,

x + 3 = 0

then, -3 + 3 = 0

Equation satisfied

If x = 9,

x + 3 = 0

but, 9 + 3 ≠ 0

Equation not satisfied

If x = 10,

x + 3 = 0

but, 10 + 3 ≠ 0

Equation not satisfied

Answer 2

Answer: here is your answer,

-3 satisfies the condition

Step-by-step explanation:

Given,

x + 3 = 0

x = -3, 9, 10

case (i) put x = -3

(-3) + 3 = 0

 L.H.S = R.H.S

case (ii) put x = 9

(9) + 3 ≠ 0

 L.H.S ≠ R.H.S

case (iii) put x = 10

(10) + 3 ≠ 0

 L.H.S  ≠ R.H.S

so, value of x is -3 as it satisfied the equation.
