The towel on the wall… It’s our ancient custom. There was not a single Ukrainian house , which would not be decorates with towels. A house without a towel was compared with a family without children. A towel symbolized not only aesthetic taste , it was a face of a house and of a hostess. The towels proved that the hostess was tidy and hard-working.
A newly-born child was handed with the towel, guests were met with bread and salt on the towel. A son , a husband, a father were seen off with the towel. While getting married the newly-formed family was standing on a towel too. Bread and salt on an embroidered towel were a symbol of hospitality of the Ukrainian people. To take the towel , to kiss bread symbolized unity, peace, love , understanding among people. This custom has a good tradition in our country.
Towel were used in different ceremonies and in everyday life as well: for wiping a face and hands, for drying dishes, for decorating the houses, for presenting dear people. The ornaments and colours of towels were different in different regions. A lot of songs about the embroidered towel have been created in Ukraine. Объяснение:

{ y - x = 42/60 | * 60
знаменатель дроби не должен быть равен 0 : х≠ 0 ; у≠0
{28y + 28x = 60xy |÷4
{60y - 60x = 42 | ÷6
{ 7y + 7x = 15xy
{ 10y - 10x = 7 ⇒ 10(y-x) = 7 ⇒ y -x = 0.7 ⇒ y = 0.7 + x
Метод подстановки:
7(0,7 + х) + 7х = 15х(0,7 +х)
4,9 + 7х + 7х = 10,5х + 15х²
4,9 + 14х = 15х² + 10,5х
15х² + 10,5х - 14х - 4,9 = 0
15х² - 3,5х - 4,9 = 0
D = (-3.5)² - 4*15 * (-4.9) =12.25 + 294 = 306.25 = 17.5²
D>0
x₁ = ( - (-3.5) - 17.5)/(2*15) = (3.5 - 17.5)/30 = - 14/30 = - 7/15
x₂ = ( - ( -3.5) + 17.5)/(2*15) = (3.5 + 17.5)/30 = 21/30 = 7/10 = 0.7
y₁ = 0.7 + (-7/15) = 7/10 - 7/15 = (21-14)/30 = 7/30
y₂ = 0.7 + 0.7 = 1.4
ответ: ( - 7/15 ; 7/30 ) , (0,7 ; 1,4 ) .
