Translating Equations

An equation is a mathematical statement that asserts the equality of two expressions, typically containing variables.

Translating a verbal expression into an equation involves converting words into mathematical symbols and expressions.

The equation is $$2n + 4 = 8$$ or $$4 + 2n = 8$$ .

The equation is $$\frac{n}{6} - 3 = 1$$ .

The equation is $$4n + 3 = 15$$ or $$3 + 4n = 15$$ .

The equation is $$6n - 9 = -15$$ .

The first step is to subtract 9 from both sides.

'Twice a number' means to multiply the number by 2, represented as $$2n$$ .

It refers to dividing the number by 6, represented as $$\frac{n}{6}$$ .

'Less than' indicates subtraction; for example, 'three less than a number n' is written as $$n - 3$$ .
