Let me give you two examples:
One Variable: x * 5 + 2 = 5x + 2
Two Variables: x * 5 + y = 5x + y
If you find out what x is in the first example, you know the answer to the equation. Say x was 23, 23 * 5 + 2 = 117 .
If you find out what x is in the second example, you do not know the answer to the equation.
Say x was 23 again, 23 * 5 + y = 115 + y
You just end up with another equation.
Say y was 23 and you did not know what x was, x * 5 + 23 = 5x + 23
You end up with an equation.
So you have to know x AND y.
So say they were both 23, 23 * 5 + 23 = 138
That is the difference, with one variable, you need to know one variable to figure out the answer.
With two variables, you need to know both to know the answer.
Three variables, all three.
It goes on like that.
I hope I answered your question!
What else can I help you with?
How do you calculate roots?
The roots of an equation in two variables is calculated by setting the dependent variable, y, equal to 0 and then solving the resulting equation for the independent variable, x. The procedure for solving the equation in x will depend on the nature of the equation.
What reduces an equation that has two variables to an equation that has one variable. It is then possible to find the solution for this variable.?
substitution
How do you solve a equation using unknown variables?
You don't use unknown variables to solve an equation. The purpose of solving an equation is to find the value of the variable so that it's no longer unknown.
What is s solving an equation?
An equation is a mathematical statement that may (or may not) be true, defined for some variables. Solving an equation is finding those values of the variables for which the equation or statement is true.
Can you solve a variable with an equation?
When an equation has a variable in it (only one), then there are only certainvalues the variable can have that will make the equation a true statement."Solving" the equation means finding those values for the variable.
What is solving equations about?
It is about finding a value of the variable (or variables) that make the equation a true statement.

Describe the procedure used to solve an equation for a variable?
It very much depends on the equation. The procedure for solving an equation with just one variable is so very different from the procedure for finding solutions to non-linear equations in several variables.
How do you solve a equation using unknown variables?
You don't use unknown variables to solve an equation. The purpose of solving an equation is to find the value of the variable so that it's no longer unknown.
How is solving a two step equation like solving one step equation?
the alikes of solving a one-step or two-step equation: in solving an equation is to have only variables on one side of the equal sign and numbers on the other side of the equal sign. The other alike is to have the number in front of the variable equal to one the variable does not always have to be x. These equations can use any letter as a variable.
What is s solving an equation?
An equation is a mathematical statement that may (or may not) be true, defined for some variables. Solving an equation is finding those values of the variables for which the equation or statement is true.
How is solving for a specified variable in a formula different to finding a solution for an equation or inequality?
With a formula, you know the variable's value, and you have to calculate the value of the function of it. With an equation, you know the function's value, and you have to calculate the value of the variable.

How is constant found?
The constant in a mathematical equation can be found by determining the value of the term that does not change across different values of the variable. This can be done by solving the equation for different values of the variable and isolating the term that remains the same.
Is the goal in solving an equation to get the variable by itself?
Yes
