Answer 1

1) пускай 1 булочка стоит х, тогда 1 бублик стоит у$\left \{ {{x+y=14} \atop {x+3y=32}} \right. \left \{ {{32-3y+y=14} \atop {x=32-3y} \right. 32-3y+y=14; -2y=14-32; -2y=-18; y=-18/-2; y=9 Значит один бублик стоит 9 рублей.$
2) таким самым способом

Answer 2

Problem 1:

The cost of a bun and three bagels is 32 rubles, while the cost of a bun and a bagel is 14 rubles. How much does one bagel cost?

To solve this problem, let's assume the cost of a bun is x rubles and the cost of one bagel is y rubles.

According to the given information, we have two equations:

1. x + 3y = 32 (equation 1) 2. x + y = 14 (equation 2)

To find the value of y, we can solve these equations simultaneously.

Subtracting equation 2 from equation 1, we get:

(x + 3y) - (x + y) = 32 - 14 2y = 18 y = 9

Therefore, one bagel costs 9 rubles.

Problem 2:

The cost of a Gulevér candy and a chocolate bar is 84 rubles, while the cost of a bar and five Gulevér candies is 196 rubles. By how many times is the chocolate bar more expensive than the Gulevér candy?

Let's assume the cost of a Gulevér candy is x rubles and the cost of a chocolate bar is y rubles.

According to the given information, we have two equations:

1. x + y = 84 (equation 1) 2. y + 5x = 196 (equation 2)

To find the value of y, we can solve these equations simultaneously.

Subtracting equation 1 from equation 2, we get:

(y + 5x) - (x + y) = 196 - 84 4x = 112 x = 28

Substituting the value of x into equation 1, we can find the value of y:

28 + y = 84 y = 56

Therefore, the chocolate bar is 56 rubles and the Gulevér candy is 28 rubles. The chocolate bar is 2 times more expensive than the Gulevér candy.
