Please help me solve this question: f+2e=-3
5f+4e=3. Using either the elimination or substitution method.

system+%28f+%2B+2e+=+-+3______eq_%28i%29%2C%0D%0A5f+%2B+4e+=+3_______eq_%28ii%29%29

Multiply eq (i) by - 2, and add both equations, OR
Multiply eq (i) by 2, and subtract one equation from the other

Either way, you will determine the value of f. Substitute that f-value into any of the two equations to determine the value of e.

You then do the check!!
