It is a ratio.
variables that allows us to preform equations with numbers.
algebra involves equations with numbers a variables and your goal is to solve for the variable
Two equations are equal when the result of the functions of the numbers and variables of one equation match the results of the other equation.
The idea is to work with the same variables, but it is possible that some of the variables are missing in some of the equations.

Numerical equations have only numbers and symbols, while algebraic equations have variables also.
Two equations are equal when the result of the functions of the numbers and variables of one equation match the results of the other equation.
The idea is to work with the same variables, but it is possible that some of the variables are missing in some of the equations.
They are alike because the both have value, they both have variables, and both have numbers. there, happy?
No, but eliminating variables is one of several ways to find the value of variables in a system of equations.
By eliminating the fractions
Simultaneous equations have at least two unknown variables.
Straight line equations have two variables in the form of x and y
A system of equations is a set of two or more equations with the same variables, graphed in the same coordinate plane
