# How To Write An Equation

Acquisition out how to break simple algebraic equations with one alien

An operation is a algebraic process. Common examples are accession ( ), addition (-), multiplication (x) or analysis (÷).

An changed operation is the adverse of the operation acclimated in the equation.

x is the adverse of ÷

÷ is the adverse of x

Let’s about-face the botheration beneath into an equation.

3 loaves of aliment and a £4 backpack of cheese amount £10. How abundant is anniversary loaf?

In this blueprint we appetite to assignment out the amount of one loaf of bread.

As the amount of aliment is the unknown, we will represent this with a x.

We charge 3 loaves of bread, so in our blueprint we will represent this with 3x.

We apperceive the cheese costs £4 and the absolute absorb is £10.

So now we can address our equation:

3x 4 = 10

When analytic an blueprint it is important to acquisition the amount of one letter.

Let’s break the blueprint 3x 4 = 10

To abolish the 4 we complete the changed (opposite) operation by adding the 4.

3x = 10 – 4

That gives us 3x = 6 (3 loaves amount £6)

To assignment out the amount of one loaf we bisect both abandon of the blueprint by 3.

x = 6 ÷ 3

So x = 2 (one loaf costs £2)
