its okay. i've uncovered my dumb mistake ;S
Solve the following simultaneous equations.
I know how to solve it by substitution but i can't seem to solve it using the elimination method.
I tried using elimination but I kept getting a fraction for my answer (which is wrong.)
Can anybody show me how to solve this using the elimination method?
Thank you very much!!! I would really appreciate the help!
There are two ways to this by elimination:
1) multiply the second equation by 2 so that both have "2y" and subtract from the first, eliminating y.
2) multiply the second equation by 4 so that both have "8x" and subtract from the first, eliminating x.
