What given?
Evaluating a polynomial is finding the value of the polynomial for a given value of the variable, usually denoted by x. Solving a polynomial equation is finding the value of the variable, x, for which the polynomial equation is true.
Finding the value of a variable involves solving an equation or a set of equations where the variable is present. This process typically includes isolating the variable on one side of the equation through various algebraic techniques, such as addition, subtraction, multiplication, and division. Once the variable is isolated, its value can be determined based on the given information. This is a fundamental concept in algebra and critical for solving mathematical problems.
Yes
in this given variable in this is x.
Solving for a variable involves isolating that variable in an equation to determine its value. This process typically includes using algebraic operations such as addition, subtraction, multiplication, or division to manipulate the equation. The goal is to express the variable in terms of known quantities or constants. For example, in the equation (2x + 3 = 11), solving for (x) would yield (x = 4).

The second step when solving a system of nonlinear equations by substitution is to solve one of the equations for one variable in terms of the other variable(s). Once you have expressed one variable as a function of the other, you can substitute that expression into the other equation to create a single equation in one variable. This allows for easier solving of the system.
substitution
the alikes of solving a one-step or two-step equation: in solving an equation is to have only variables on one side of the equal sign and numbers on the other side of the equal sign. The other alike is to have the number in front of the variable equal to one the variable does not always have to be x. These equations can use any letter as a variable.
The term that is given to the variable being measured in an experiment is the dependent variable. This variable is the one that is observed and recorded based on the changes in the independent variable.
A number that one is solving for-the unknown.
The coefficients can be any numerical constants.
