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.
(x/2) × 5 = 20
5x / 2 = 20
5x = 40
Divide 5 on both sides of the equation 5x = 40
x = 8
