Question

(x + 9,14) : 7,2 = 5 с проверкой

Answer 1

Решение:(x + 9,14): 7,2=5

X+ 9,14=5 x 7,2

X + 9,14=36

X=36-9,14

X=26,86

Проверка:(26,86+9,14):7,2+5

5=5

Answer 2

To solve the given equation with the point (x + 9, 14) and the values 7, 2, and 5, we can use the concept of proportionality. Let's break down the equation step by step:

(x + 9, 14) : 7, 2 = 5

Here, (x + 9, 14) represents the point (x + 9, 14), and we need to find the value of x that satisfies the equation.

To solve this, we'll set up a proportion using the given values:

(x + 9) / 7 = 2 / 5

Now, we can cross-multiply and solve for x:

5(x + 9) = 7 * 2

5x + 45 = 14

Subtracting 45 from both sides:

5x = 14 - 45

5x = -31

Dividing both sides by 5:

x = -31 / 5

x = -6.2

Therefore, the value of x that satisfies the equation is x = -6.2.

To verify this solution, we can substitute x = -6.2 back into the original equation:

((-6.2) + 9) / 7 = 2 / 5

(2.8) / 7 = 2 / 5

0.4 = 0.4

The equation holds true, confirming that the solution x = -6.2 is correct.
