The answer depends on the form of the equation and the domain.
For example,
There are many other equations in one variable for which cannot be solved.
However, for simple equations, you may get a solution by making the same changes to both sides of the equation (with some exceptions, like division by zero, or taking square roots, etc) until you rename one side as the variable.
For example, to solve
(2x + 3)/5 = 9
Multiply both sides by 5: 2x + 3 = 45
Subtract 3 from both sides: 2x = 42
Divide both sides by 2: x = 21.
Solution of inequalities is the same except that if you multiply or divide by a negative number then the inequality changes direction.
To solve a linear equation or inequality, first isolate the variable on one side of the equation or inequality. For an equation, use operations like addition, subtraction, multiplication, or division to simplify until the variable is alone (e.g., (ax + b = c) becomes (x = (c-b)/a)). For an inequality, follow similar steps but remember to reverse the inequality sign if you multiply or divide by a negative number. Finally, express the solution in interval notation or as a graph on a number line, depending on the context.
To isolate a variable in an equation or inequality, you need to perform inverse operations to both sides. Start by eliminating any constants added or subtracted from the variable, followed by dividing or multiplying to remove coefficients. Ensure to maintain the equality or inequality by performing the same operations on both sides. Finally, simplify the expression to get the variable alone on one side.
you can only solve for one in an equation so it can equal something
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.
To solve a system of equations by substitution, first solve one of the equations for one variable in terms of the other. Then, substitute this expression into the other equation. This will give you an equation with only one variable, which you can solve. Finally, substitute back to find the value of the other variable.

This will give you an equation with only one variable, which you can solve. Finally, substitute back to find the value of the other variable.
To use substitution to solve a problem, first, identify one equation in a system of equations and solve it for one variable in terms of the other(s). Next, substitute this expression into the other equation(s) to eliminate the variable. This results in a single equation with one variable, which you can then solve. Finally, substitute back to find the values of the other variables.

To solve a system of equations using the substitution method, first, solve one of the equations for one variable in terms of the other. Then, substitute this expression into the other equation to eliminate that variable. This will result in a single equation with one variable, which can be solved for its value. Finally, substitute this value back into the original equation to find the value of the other variable.
You can write an equivalent equation from a selected equation in the system of equations to isolate a variable. You can then take that variable and substitute it into the other equations. Then you will have a system of equations with one less equation and one less variable and it will be simpler to solve.
This cannot be solved. Just like an equation, an inequality has to have at least one variable and at least one operator, such as less than, greater than, etc. Yours has no operator. Please restate your question.
