Question

1,6(7-5х)+4(2-0,4х)=0

Answer 1

Ответ:x=2

Пошаговое объяснение:

1,6(7-5х)+4(2-0,4х)=0

11,2-8x+8-1.6x=0

19,2-9,6=0

-9,6=19,2

x=-19,2/-9,6

x=2

Answer 2

To solve the equation, let's simplify and solve for the value of 'x':

1. Distribute the numbers inside the parentheses: 1 * 7 - 1 * 5x + 4 * 2 - 4 * 0.4x = 0

2. Simplify the equation further: 7 - 5x + 8 - 1.6x = 0

3. Combine like terms: -5x - 1.6x + 7 + 8 = 0

4. Add the constants and coefficients separately: -6.6x + 15 = 0

5. Now, isolate 'x' by moving the constant to the other side of the equation: -6.6x = -15

6. Finally, divide both sides by the coefficient of 'x' to find the value of 'x': x = -15 / -6.6

x ≈ 2.27 (rounded to two decimal places)

So, the solution to the equation is approximately x = 2.27.
