Solve by the elimination method:


0.4x+0.5y= -29/19 (fraction)??
Please Help I do not understand Algebra!!

  • algebra -

    to solve this equation by elimination method, you need to make sure that the number in each one of the equation is the same.
    you have to pick a no that will fit.



    you then cross out the no that is the same and what you have let is:

    then you subtract the remaining equation, so it will be:


    the answer you get will be divided by 2.3y and that is how you get the value of y

    after you get the value of y, you substitute the value of y into one of the equation that was not multiplied by any no, which is the original equation, then you get the value of x .and yeah that's all. i hope this was helpful
