The solution to a system of simultaneous equations is the values of the variables that make all the equations in the system true.

Simultaneous equations are a set of two or more equations with the same variables. These equations are solved together to find the values of the variables that satisfy all the equations at the same time.

What is a simultaneous eq'n

The elimination method for solving simultaneous equations involves adding or subtracting the equations in such a way that one of the variables is eliminated, leaving an equation with only one variable. This equation can then be solved for its value, and the value can be substituted back into one of the original equations to find the value of the other variable.The elimination method for solving simultaneous equations involves adding or subtracting the equations in such a way that one of the variables is eliminated, leaving an equation with only one variable.

​Elimination Method

The substitution method for solving simultaneous equations involves replacing the value of one variable in one equation with the expression for that variable from another equation. This creates an equation that only contains one variable, which can then be solved for its value. Once the value of one variable is known, it can be substituted back into one of the original equations to find the value of the other variable.

​ This was just a clean up on simultaneous eq'ns. When i get time i'll go into the elimination method. As for right now i'll just end with a few questions ;)
