What is the value of x? a)3 b)4 c)6 d)8: (x/2) × 5 = 20

An equation is a mathematical statement with an 'equal to' symbol between two algebraic expressions that have equal values.

Answer: x = 8

An equation is like a weighing balance with equal weights on both sides. If we add or subtract the same number from both sides of an equation, it still holds.

Explanation:

(x/2) × 5 = 20

5x / 2 = 20

5x = 40

Divide 5 on both sides of the equation 5x = 40

x = 8

So, the required value of x is 8
