Resolver las ecuaciones lineales


(Definiciones:)

Variable:

a number that you don't know, often represented by "x" or "y" but any letter will do!
Linear
Expression:

a mathematical statement that performs functions of addition, subtraction, multiplication, and division
However, variable(s) in linear expressions

  • Cannot have exponents (or powers)
    For example, x squared or x 2

  • Cannot multiply or divide each other
    For example:  "x" times "y" or xy; "x" divided by "y" or x/y

  • Cannot be found under a root sign or square root sign (sqrt)

These are examples of linear expressions:

x + 4

2x + 4

2x + 4y

These are not linear expressions:

x2

(no exponents on variables)

2xy + 4

(can't multiply two variables)

2x / 4y

(can't divide two variables)

Ö x

(no square root sign on variables)
Linear
Equation:

 a mathematical expression that has an equal sign and linear expressions
