Question

Помогите решить задачу. На трех участках посадили 126 кустов смородины (всего). На первом и втором 87 кустов. На первом и третьем 68 кустов. Сколько кустов на каждом участке?

Answer 1

126-87=39(к) - на ІІІ участке
126-68=58(к) - на ІІ участке
87-58=29(к) - на І участке

Answer 2

Solving the Problem of Planting Currant Bushes

To solve the problem of how many currant bushes were planted on each plot, we can use the information provided.

1. Total Number of Currant Bushes: 126 bushes were planted in total.

2. Number of Bushes on the First and Second Plots: 87 bushes were planted on the first and second plots.

3. Number of Bushes on the First and Third Plots: 68 bushes were planted on the first and third plots.

Let's calculate the number of bushes on each plot using this information.

Calculation

Let's denote the number of bushes on the first plot as x, the number on the second plot as y, and the number on the third plot as z.

We have the following information: - x + y = 87 (Equation 1) - x + z = 68 (Equation 2) - x + y + z = 126 (Equation 3)

We can solve these equations to find the values of x, y, and z.

Solution

Subtracting Equation 2 from Equation 1, we get: y - z = 19 (Equation 4)

Adding Equation 2 and Equation 4, we get: 2x + 2y = 155 x + y = 77.5 (Equation 5)

Substituting the value of x + y from Equation 5 into Equation 3, we get: 77.5 + z = 126 z = 126 - 77.5 z = 48.5

Now we can calculate the values of x and y: x = 77.5 - 48.5 x = 29 y = 87 - 29 y = 58

Conclusion

So, the number of currant bushes planted on each plot is: - 29 bushes on the first plot - 58 bushes on the second plot - 48.5 bushes on the third plot
