@ChmE Please help!
are you sure you wrote the options correctly?
and the question?
In elimination, you want to add or subtract the equations to eliminate one variable, here it's y. Your instinct is correct, but you have to be careful which equation you multiply by what. You want 12y or -12 y. The first equation should be multiplied by 4 or -4 and the second by 3 or -3. Notice they give you 3 with the second eq and 4 with the first one. That will not help. 5 and -7 would help eliminate x not y.
which is why i think the question or options are wrong
Right, and i would think it would be -3 and 4 so I'm going to go ahead and go with none of the above
either the question should be eliminate x first or the option should have multiply first equation by 4 and second by 3 or multiply first equation by -4 and second by -3 or something like that
oops i didnt even see none of the above so yes thats the answer
Thanks so much!
definitely non of the above. You're correct
It's tough to answer these questions without knowing if they want to eliminate by addition or subtraction. Subtraction the coefficients should have the same sign. Addition they should be opposite.
