Question

0,6-1,6*(x-4)=3*(7-0,4x)

Answer 1

Ответ:-35

Пошаговое объяснение:

0,6-1,6*(x-4)=3*(7-0,4x)

0,6-1,6х+6,4=21-1,2x

7-1,6x=21-1.2x

-1.6x+1.2x=21-7

-0.4x=14

x=-35

Answer 3

To solve the equation for $x$, follow these steps:

Given equation: $0.6 - 1.6 \cdot (x - 4) = 3 \cdot (7 - 0.4x)$

Step 1: Distribute the multiplication on both sides of the equation: $0.6 - 1.6x + 6.4 = 21 - 1.2x$

Step 2: Group like terms on each side of the equation: $-1.6x + 0.6 + 6.4 = 21 - 1.2x$

Step 3: Combine constants on both sides of the equation: $-1.6x + 7 = 21 - 1.2x$

Step 4: Move $x$ terms to one side by adding $1.2x$ to both sides: $-1.6x + 1.2x + 7 = 21$

Step 5: Simplify and combine $x$ terms: $-0.4x + 7 = 21$

Step 6: Subtract $7$ from both sides: $-0.4x = 14$

Step 7: Divide both sides by $-0.4$ to solve for $x$: $x = -\frac{14}{0.4}$

Step 8: Simplify the fraction: $x = -\frac{35}{2}$ or $x = -17.5$

So, the solution for the equation is $x = -17.5$.
