amistre64 · Answer

trivial but fun :)

$2x + 5y = 8$; /8

$\cfrac{2x}{8} + \cfrac{5y}{8} = \cfrac{8}{8}$; simplify

$\cfrac{x}{4} + \cfrac{5y}{8} = 1$; just drop that "5" under

$\cfrac{x}{4} + \cfrac{y}{8/5} = 1$; just drop that "5" under

read the intercepts from the bottoms

anonymous · Answer

took a second or 2 to render and got "just drop that "5" under" twice, but it's fine.
