What are the ways to solve a system of linear equations in two variables?

the substitution method in which you take each variable and you find out the value and then plug it into the original equation.the adding and subtracting method in which you subtract\add equations to take out a variable and you can figure out what the other variable is. then you also substitute that into that into the original variable


How do you solve simultanious equations?

By eliminating or substituting one of the variables in the two equations in order to find the value of the other variable. When this variable is found then substitute its value into the original equations in order to find the value of the other variable.


How can you find a variable in math?

You find, or construct, an equation or set of equations which express the unknown variable in terms of other variables.

How do you solve this equations 4x plus 5 equals 13?

4x + 5 = 13. To solve algebraic equations, you need to get the variable by itself on one side of the equation. Start by subtracting 5 from both sides >>> 4x = 8. Then divide both sides by 4 to find what 'x' equals >>> x = 2.
