Question

Solve the equation: 3s + 12 = 0

• A. s = 3
• B. s = 4
• C. s = -4
• D. s = -3

Answer 1

The correct option is C s = -4

$3s+12=0$

Subtracting 12 from both the sides of the equation, we get

$3s+12–12=0-12$

$\Rightarrow 3s=-12$

Now, dividing both the sides by 3, we get

$\frac{3s}{3}=\frac{-12}{3}$

$\Rightarrow s=-4$
