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
