Algebra Calculator shows you the step-by-step solutions! Solves algebra problems and walks you through them.
How to Evaluate the Expression in Algebra Calculator. First go to the Algebra Calculator main page. Type the following: First type the expression 2x. Then type the @ symbol. Then type x=3. Try it now: 2x @ x=3. Clickable Demo. Try entering 2x @ x=3 into the text box.
To solve an algebraic expression, simplify the expression by combining like terms, isolate the variable on one side of the equation by using inverse operations. Then, solve the equation by finding the value of the variable that makes the equation true.
To simplify your expression using the Simplify Calculator, type in your expression like 2(5x+4)-3x. The simplify calculator will then show you the steps to help you learn how to simplify your algebraic expression on your own.
Algebra Calculator can evaluate expressions that contain the variable x. To evaluate an expression containing x, enter the expression you want to evaluate, followed by the @ sign and the value you want to plug in for x.
1. Here, we show you a step-by-step solved example of algebraic expressions. This solution was automatically generated by our smart calculator: $f\left (x\right)=x^2+x$. 2. Factor the polynomial $x^2+x$ by it's greatest common factor (GCF): $x$. $f\left (x\right)=x\left (x+1\right)$.
To solve a rational expression start by simplifying the expression by finding a common factor in the numerator and denominator and canceling it out. Then, check for extraneous solutions, which are values of the variable that makes the denominator equal to zero.
