An equation that contains at least one variable is (2x + 5 = 15). In this equation, (x) is the variable, and the equation states that when you multiply (x) by 2 and add 5, the result equals 15. Solving for (x) will allow you to find its value.
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.
substitution
To isolate a variable on one side of an equation, you can perform inverse operations to eliminate other terms. Start by adding or subtracting constants from both sides to move them away from the variable. Then, if the variable is multiplied by a coefficient, divide both sides by that coefficient. Repeat these steps as necessary until the variable stands alone.
To solve equations with variables on both sides, first isolate the variable by moving all terms involving the variable to one side of the equation and constant terms to the other side. This can be done by adding or subtracting terms as necessary. Once the variable is isolated, simplify the equation if needed and solve for the variable. Finally, check your solution by substituting it back into the original equation.

Literal Equation
it is a one-step equation
Simultaneous equation* * * * *No, simultaneous equations are two or more equations that have all to be true at the same time (simultaneously) for the solution.An equation with more than one variable is a multivariate equaion.Area = 0.5*Length*Height or a = 0.5*l*h for the area of a triangle has more than one variables, but it is certainly not simultaneous.An equation with a variable is called a single variable equation. An equation that has more than one variable is called as a multi-variable equation. A polynomial equation has one variable in different powers: a common example is quadratic equations.
linear equation in one variable
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.
substitution
It is to make the variable the subject of the equation.
Isolating a single variable in terms of the rest of the equation provides a solution to that variable. That is, if you know the equation that equals the variable, then you can figure out its value.
rRestate the equation as A = 3.14r2.The independent variable is the one you are given - in this case, 'r'.The dependent variable is the one you have to work out (it depends on the other variable). In this case, A.
