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.
What else can I help you with?
How do you solve one variable equations?
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.
How do you use substitution to solve equations?
You plug in what the variable is equal to for that variable then you will be able to finish the problem
How do you find equivalent rate?
You set the two equations equal to each other and then solve for the variable.
How can you use equations with the variable on both sides to solve real-world problems?
Equations with variables on both sides can effectively model real-world situations where two quantities are equal, such as budgeting, profit calculations, or distance and time problems. To solve these equations, you can isolate the variable by performing the same operations on both sides, allowing you to find the unknown value. This approach helps in determining optimal solutions, making informed decisions, and analyzing relationships between different factors in practical scenarios. For example, setting up an equation to balance costs against revenue can guide financial planning.
How do you solve system of eqaution by subsitution?
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.

Can you solve a system of equations you can replace a variable with an equal value or expression true or false?
True
To solve a system of equations you cannot replace a variable with an equal value or expression?
You can replace a variable with an equal value or expression. Just make sure the same variable always gets the same value or expression.
How does writing equivalent equations help you solve a system of equations?
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.
How doI solve system of equations by substitution?
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.
Four steps to the elimination method?
There are four steps in an algebraic elimination problem. These steps are: to find a variable with equal or opposite coefficients, if equal then subtract the equations but if opposite then add, solve one variable equation left, and then substitute known variable into other equation and solve. hi
What do you use to solve for the unknown variable?
Equations are used to find the solution to the unknown variable.
