Solve for x: the quantity of x plus 20 over 2 = 3x

The question is based on simplifying an algebraic expression.

Answer: x = 4 satisfies the given equation: the quantity of x plus 20 over 2 = 3x

The given equation can be solved by interpreting the given information mathematically.

Explanation:

Given that, x plus 20 over 2 = 3x

Therefore, (x + 20) / 2 = 3x

(x + 20) = (3x) × 2

x + 20 = 6x

6x - x = 20

5x = 20

x = 20/5

x = 4

Thus, x = 4 satisfies the given equation.
