Question

0,6(3+х)-0,7(х-4)=19,3-2,6х

Answer 1

0,6(3+х)-0,7(х-4)=19,3-2,6х

1,8+0,6х-0,7х+2,8=19,3-2,6х

2,5х=14,7

х=5,88

Answer 2

Ответ:

Пошаговое объяснение:

1,8+0,6х-0,7х+2,8=19,3-2,6х

0,6х-0,7х+2,6х=19,3-1,8-2,8

2,5х=14,7

х=14,7/2,5

х=5,88

Answer 3

To solve the equation $0.6(3+x) - 0.7(x-4) = 19.3 - 2.6x$, follow these steps:

1. Distribute the constants and variables inside the parentheses: $1.8 + 0.6x - 0.7x + 2.8 = 19.3 - 2.6x$

2. Combine like terms on both sides of the equation: $0.6x - 0.7x + 1.8 - 2.8 = 19.3 - 2.6x$

   $-0.1x - 1.0 = 19.3 - 2.6x$

3. Add $2.6x$ to both sides to isolate the $x$ term: $-0.1x + 2.6x - 1.0 = 19.3 - 2.6x + 2.6x$

   $2.5x - 1.0 = 19.3$

4. Add $1.0$ to both sides: $2.5x - 1.0 + 1.0 = 19.3 + 1.0$

   $2.5x = 20.3$

5. Divide by $2.5$ to solve for $x$: $\frac{2.5x}{2.5} = \frac{20.3}{2.5}$

   $x = 8.12$

So, the solution to the equation $0.6(3+x) - 0.7(x-4) = 19.3 - 2.6x$ is $x = 8.12$.
