Best ResponseYou've already chosen the best response.0What ? How would i do that .. Do i multiply 102 by 2 ??? I am soooo confused , i have been reading all my lessons and doing all my work i just don't get it, it makes no sense to me ...

Best ResponseYou've already chosen the best response.2Well actually there are to methods, the use of simultaneous equations that i used above and using substitution...

Best ResponseYou've already chosen the best response.2*2 methods Using substitution: \[\large m+w= 102\]\[\large \implies w=102m\] put that in 2nd equation

Best ResponseYou've already chosen the best response.2\[\large \implies 2m306+3m=6\]\[\large \implies 5m=3066\]\[\large \implies 5m=300\]

Best ResponseYou've already chosen the best response.2\[\Large m=60\]\[\Large w={\large 10260}=42\] Using simultaneous equations:\[\large m+w=102\]\[\large \implies 2m+2w=204\] Subtracting the second equation:\[\Large \begin{matrix}2m+2w=204 \\ 2m3w=6 \\ \ \ \ \ \ \ \ +\ \ \ \ \ \ \ \ +\ \ \ \ \ \ \\ \overline{\ \ \ \ \ \ \ \ \ \ 5w=210}\end{matrix}\]
