WebHow 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. … Weby=13-2x Now you can substitute (13-2x) for the y in the first equation.-3(13-2x)+4x=11 Then you can solve for x. After finding x, Then substitute that answer for x in either equation and solve for y. The substitute both answers into the other equation to double check. If the equation is in balance, you have the correct answers. I hope that helps.
