How did you know that the values of variable raelly satisfy the equation?
You substitute the value of the variable into the equation and simplify. If the rsult is a true statement then that value of the variable really does satisfy the equation.
What is dependent quantity means in math?
A variable that depends on one or more other variables. For equations such as y = 3x - 2, the dependent variable is y. The value of y depends on the value chosen for x. Usually the dependent variable is isolated on one side of an equation. Formally, a dependent variable is a variable in an expression, equation, orfunction that has its value determined by the choice of value(s) of other variable(s).
What is the value for a variable that makes an equation?
It's the value that when substituted in for the variable, makes the equation true. Ex: x + 1 = 3 The value 2, when substituted for the variable x, makes the equation true.
The value of a variable which satisfies an equation is called to the equation?
a solution
Why do you isolate the variable on one side the the equation when solving a linear 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.
How is solving for a specified variable in a formula different to finding a solution for an equation or inequality?
With a formula, you know the variable's value, and you have to calculate the value of the function of it. With an equation, you know the function's value, and you have to calculate the value of the variable.
How do I plug in a variable?
You cannot plug in a variable, what you do is plug in the value for a variable. If you know the value of the variable in an equation (or formula), the process of replacing that variable whenever it appears in the equation by its value is called plugging in the value for the variable.
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.

Usually the dependent variable is isolated on one side of an equation. Formally, a dependent variable is a variable in an expression, equation, orfunction that has its value determined by the choice of value(s) of other variable(s).
What is an equation that is not true for any value of a variable?
linear equation in one variable
What relationship does a linear graph shows?
A linear graph shows a linear equation in which the value of one variable depends on the value of the other variable.
What is the value for a variable that makes an equation?
It's the value that when substituted in for the variable, makes the equation true. Ex: x + 1 = 3 The value 2, when substituted for the variable x, makes the equation true.
How is constant found?
The constant in a mathematical equation can be found by determining the value of the term that does not change across different values of the variable. This can be done by solving the equation for different values of the variable and isolating the term that remains the same.
How is solving for a specified variable in a formula similar to finding a solution for an equation or inequality?
With a formula, you know the variable's value, and you have to calculate the value of the function of it. With an equation, you know the function's value, and you have to calculate the value of the variable.
What is the value of the variable that makes equations true?
The value of the variable that makes an equation true is known as the solution to the equation. It is the number that, when substituted for the variable, satisfies the equation's conditions. To find this value, one typically manipulates the equation using algebraic techniques until the variable is isolated on one side. The resulting value can then be verified by substituting it back into the original equation.
What is The value of the variable that makes an equation true is a?
The value of the variable that makes an equation true is known as the "solution" to the equation. For example, if you have the equation (x + 3 = 7), the solution is (x = 4), since substituting 4 into the equation yields a true statement. In general, finding the value of the variable involves manipulating the equation to isolate the variable on one side.
