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