It means that you manipulate the equation in such a way that the variable appears only on one side, by itself.
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.
The variables may have different values.
To solve equations effectively in four steps, consider these types: Linear Equations: Isolate the variable by adding or subtracting terms, then divide or multiply to solve. Quadratic Equations: Rearrange to standard form, factor or use the quadratic formula, simplify, and solve for the variable. Rational Equations: Clear the denominators, simplify the resulting equation, isolate the variable, and solve. Exponential Equations: Take the logarithm of both sides, isolate the variable, and simplify to find the solution. Systems of Equations: Use substitution or elimination to reduce the system, isolate one variable, and solve for it.
Solving for one variable makes it easy to put in a value for the other variables, and find a value for the first variable.
You first have to get rid of the numbers that don't have variables. then you divide by the variable and solve for it.
Rearrange the formula so that the indicated variable is the subject of the mathematical formula.
The answer will depend on the exact form of the formula.

Sometimes we are given a formula, such as something from geometry, and we need to solve for some variable other than the "standard" one. For instance, the formula for the perimeter P of a square with sides of length s is P = 4s. We might need to solve this equation for s because we have a lot of squares' perimeters, and we want to plug those perimeter values into one formula and have that formula (maybe in our graphing calculator) spit out the value for the length of each square's side. This process of solving a formula for a specified variable is called "solving literal equations".

Solving for one variable makes it easy to put in a value for the other variables, and find a value for the first variable.
You first have to get rid of the numbers that don't have variables. then you divide by the variable and solve for it.
To solve one-variable equations, isolate the variable on one side of the equation using algebraic operations. You can do this by adding, subtracting, multiplying, or dividing both sides of the equation by the same number, ensuring to maintain the equality. Simplify both sides as needed, and check your solution by substituting it back into the original equation to verify that both sides are equal.

Assuming the simplest case of two equations in two variable: solve one of the equations for one of the variables. Substitute the value found for the variable in all places in which the variable appears in the second equation. Solve the resulting equation. This will give you the value of one of the variables. Finally, replace this value in one of the original equations, and solve, to find the other variable.
