Ответ:

Пошаговое объяснение:

Пусть х и у искомые числа

х - у = (х + у):2

2(x - y) = x + y

2x - 2y = x + y

2x - x = y + 2y

x = 3y

x/y = 3

6. Time, November 21, 1994

Last week a simmering american electorate, angry at a washington establishment more concerned with serving the vested interests that pay for its campaigns that with the declining living standards and perceived moral decay of the rest of america, stormed into polling booths across the country and chucked much of the nation's governing class out of the window. Cone was 40 years long democratic control of the lower house of congress. Gone was the speaker of the house of representatives. Gone were democratic governers in 11 states. And if not gone, certainly drastically diminished was the prospect william clinton's gaining a second term as president.
Replacing the democratic liberals was a herd of republicans, led by the china-and-crystal-smashing congressman from suburban atlanta, newt gingrich, the next speaker of the house, who, after a short burst of conciliation on election night, seemed disinclined to throw bill clinton a rope.
Gingrich and other republicans have reasons to be cocksure of their standing. Not a single republican member of the senate or the house was defeated at the last week election. The anger of the electorate was anything if not obvious.
The top 20% of the country's income earners control half the country's wealth, and only that group's real income has been increasing over the past two decades. These numbers fuel a growing us-vc.-them psychology in the electorate. Clinton did understand this when he campaigned for presidency in 1992. But once in office, clinton seemed not so much a friend of the "little guys" as a captive of the economic and cultural elites. Most disastrously for clinton his ambitious healthcare proposal, while rightly aimed at one of the prime causes of middle-class anxiety, was easily made to look like the epitome of tax-and-spend liberal programs.
