I have an algebra problem where I need to find X, hopefully someone can help as I cannot see the wood for the trees on this one.
THanks for any help anyone
X - ((0.2*X) + (0.3*X)) = 100
"I cannot see the wood for the trees." Nice expression ^^
$\displaystyle X-((0.2X)+(0.3X))=100$
$\displaystyle \implies X(1-(0.2+0.3))=100$
$\displaystyle \implies X=\frac{100}{(1-(0.2+0.3))}$
$\displaystyle \implies X=\frac{100}{0.5}$
$\displaystyle \implies X=200$
