Question

solve: $2x = 10$ a) 2 b) 5 c) 10 d) 20

Explanation:

Step1: Isolate x by dividing both sides by 2

To solve for \( x \) in the equation \( 2x = 10 \), we divide both sides of the equation by 2. This is based on the property of equality which states that if we perform the same operation on both sides of an equation, the equality still holds. So we have:
\( \frac{2x}{2} = \frac{10}{2} \)

Step2: Simplify both sides

Simplifying the left side, \( \frac{2x}{2} \) simplifies to \( x \). Simplifying the right side, \( \frac{10}{2} = 5 \). So we get \( x = 5 \).

Answer:

B) 5
