Writing algebraic equations

An algebraic equation is a mathematical statement that shows the equality of two expressions, typically involving variables and constants.

To 'decrease' a number means to subtract a certain value from it.

You represent 'four times a number' as 4x, where x is the number.

The standard form of an equation is typically written as Ax + By = C, where A, B, and C are constants.

You express 'a number increased by 16' as n + 16, where n is the number.

'One-fourth of a number' means to multiply the number by 1/4, represented as $$\frac{1}{4}x$$ .

You write it as 7x, where x is the number.

'Is equal to' indicates that the two sides of the equation have the same value, represented by the '=' sign.

You represent '5 less than a number' as n - 5, where n is the number.

The first step is to isolate the variable on one side of the equation.
