What do you call replacing a variable in an expression by a number and simplifying the result?
That is called 'solving'.
What reduces an equation that has two variables to an equation that has one variable. It is then possible to find the solution for this variable.?
substitution
How do use substitution when solving system of equations?
You use substitution when you can solve for one variable in terms of the others. By substituting, you remove one variable from the equation, which can then be solved. Once you solve for one variable, you can use substitution to find the other.
Can algebraic expression be solved?
Yes, algebraic expressions can be solved, depending on the type of expression and the variable(s) involved. If the expression has a single variable, it can typically be solved for that variable using algebraic techniques such as simplifying, factoring, or isolating the variable. However, if the expression has multiple variables or complex operations, solving it may require more advanced algebraic techniques or numerical methods.
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 is the difference between simplifying an expression and evaluating an expression?
When you simplify, you are just taking the equation down to it's simplest form, not solving it. Evaluation involves actually solving the problem.

What is the difference between simplifing an expression and solving an equation?
An equation is a ploblem with no answer and an expression is a problem with an answer so you'll get different answers with an equation and an expression.
How do you solve inequallities?
Solving inequalities is quite similar to solving equalities - you try to isolate the variable on one side. The main difference is that if you multiply (or divide) by a negative number, you have to invert the inequality. Here is an example: -2x + 3 > 11 Subtract 3 from each side: -2x > 8 Divide both sides by (-2) - note that this involves inverting the sign: x < -4 Inverting the inequality can be tricky if you have to multiply or divide by a variable expression. You may have to consider both cases - that the expression is positive, and that it is negative.
How is solving a two step equation like solving one step equation?
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.
