Question

If ax+b=0, then x =

• A. -a
• B. a
• C. \(\frac{b}{a}\)
• D. \(-\frac{b}{a}\)

Answer 1

The Correct Option is D

We are given a linear equation in one variable: \( ax + b = 0 \)

Step 1: Subtract \( b \) from both sides of the equation \( ax = -b \)

Step 2: Divide both sides by \( a \) to isolate \( x \) \[ x = \frac{-b}{a} \]

The correct option is (D): \(-\frac{b}{a}\)
