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.
How do you use substitution to solve a problem?
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.
How do you solve system of equations by using the substitution method?
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.
What do I replace a variable with a number?
To replace a variable with a number, simply identify the variable in your equation or expression and substitute it with the desired numerical value. For example, if you have the expression ( x + 5 ) and you want to replace ( x ) with 3, you would write it as ( 3 + 5 ). This substitution allows you to evaluate the expression or solve an equation more easily.
When do you divide to isolate the variable?
You divide to isolate the variable when the variable is being multiplied by a number or expression. By dividing both sides of the equation by that number or expression, you can simplify the equation and solve for the variable. This step is commonly used in algebra to maintain balance in the equation while isolating the desired variable on one side. Always ensure that the number you are dividing by is not zero, as division by zero is undefined.
Can you solve for a variable in an expression?
No, you can only simplify an expression. To solve for a variable, it must be in an equation.
Solve for a variable in an expression x plus 5?
An expression cannot be solved; an equation or an inequality may be.
Can you solve for a variable in an equation?
Sure. You can always 'solve for' a variable, and if it happens to be the only variable in the equation, than that's how you solve the equation.

Can you solve an variable in an equation?
You may want to be a little more specific about what your question is asking....... you can solve a variable in an equation or expression. For example: 1+2=y just remember, you arnt necessarily "solving" a variable, but I guess you could say that considering a variable can change continuously. Be sure to consider that if you do "solve" a variable you end up with a constant ( a never-changing number) therefore, it is no longer a variable, but just an answer. Hope that helped! :-)
What number when substituded for the variable in an equation makes the equation true?
you have to solve the actual equation in order to answer this about your variable
What should be added to both sides of this equation to solve for the variable 76-43 plus x?
Without an equality sign the given expression can't be considered to be an equation.
How to find explicit expression?
To find an explicit expression for a mathematical relationship, start by identifying the dependent and independent variables. Use algebraic manipulation to isolate the dependent variable on one side of the equation, if possible. If the relationship is defined by a function or equation, solve it step by step to express the dependent variable in terms of the independent variable. Finally, verify your expression by substituting back into the original equation to ensure consistency.
When using the substitution to solve nonlinear system of equations you should first see if you can one variable if you can one variable in one of the equation in the system?
The general idea is to solve one of the equations for one variable - in terms of the other variable or variables. Then you can substitute the entire expression into another equation or other equations; as a result, if it works you should end up having one less equation, with one less variable.
