    does anyone know?

    find the value of x?

    1. 7x+3=10x-9

    2. 4x+6=6x-3

    Answer for 1 is 4 and answer for 2 is 4.5. To see how and why, go here:

    1 unknown variable equations

    Enter each equation on the respective side of the equal sign. Follow the math and let me know if you have questions.

    nice link. it actually gives you the steps. did you program this yourself? what kind of equations can it solve, besides linear, one-variable ones?

    I pasted this in from the instructions at the top of the page.

    This calculator solves for an equation with 1 unknown with a maximum of 2 terms on either side of the equal sign. The terms the calculator can handle are c, cx, and cx + c where c is a constant and x is any variable from (a-z).

    I programmed all lessons myself. I'm going to enhance that lesson soon to handle fractions as well.

    As for polynomials and equations in that order, I'm actively working on that over the next few weeks.

    There are other lessons on the algebra page that handle 2 unknown substitution, elimination. There is a quadratic solver as well as a cubic on the algebra page as well. I'm working on a quartic later this month.

    As I complete, test, and release more polynomial and advanced equation solution lessons, I'll dump them in the Computer Software forum for everybody's benefit.
