Question

-(3K-2/3)+(5/6+2k)=17/183*(0,4-2,3x)-0,8*(6+2x)=13,4​

Answer 1

Ответ:

1) -(3k-2/3) +(5/6+2k)=17/18

-3k+2/3+5/6+2k=17/18

-3k+2k+4/6+5/6=17/18

-1k+3/2=17/18

-k=17/18-3/2

-k=-5/9

k=5/9

2) 3*(0,4-2,3x)-0,8*(6+2x)=13,4

1,2-6,9x-4,8-1,6x=13,4

-3,6-8,5x=13,4

-8,5x=13,4+3,6

-8,5x=17

x=-2

Answer 2

It seems you have an equation with variables 'K' and 'x'. Let's simplify and solve it step by step:

First, let's simplify the equation:

-(3K - 2/3) + (5/6 + 2K) = (17/183) * (0.4 - 2.3x) - 0.8 * (6 + 2x) = 13.4

Now, we can start solving it:

1. Distribute the constants on the right side of the equation:

-(3K - 2/3) + (5/6 + 2K) = (17/183) * 0.4 - (17/183) * 2.3x - 0.8 * 6 - 0.8 * 2x = 13.4

2. Combine like terms on both sides of the equation:

-3K + 2/3 + 5/6 + 2K = (0.68/183) - (39.2/183)x - 4.8 - 0.8 * 2x = 13.4

3. Combine the fractions on the left side:

(-18K + 4 + 5) / 6 = (0.68/183) - (39.2/183)x - 4.8 - 1.6x = 13.4

4. Combine the constants on the left side:

(-18K + 9) / 6 = (0.68/183) - (39.2/183)x - 4.8 - 1.6x = 13.4

5. Multiply both sides by 6 to eliminate the fraction on the left side:

-18K + 9 = (6 * 0.68/183) - (6 * 39.2/183)x - 6 * 4.8 - 6 * 1.6x = 13.4 * 6

6. Simplify further:

-18K + 9 = 4.48/183 - (235.2/183)x - 28.8 - 9.6x = 80.4

7. Now, let's isolate the terms with 'x' on one side:

-18K + 9 + 28.8 = 4.48/183 - 80.4 + (235.2/183)x - 9.6x

8. Combine constants on the left side:

-18K + 37.8 = 4.48/183 - 80.4 + (235.2/183)x - 9.6x

9. Move constants to the right side:

-18K = 4.48/183 - 80.4 + (235.2/183)x - 9.6x - 37.8

10. Combine constants on the right side:

-18K = (-75.92/183) + (235.2/183)x - 9.6x - 37.8

11. Now, divide both sides by -18 to solve for 'K':

K = ((-75.92/183) + (235.2/183)x - 9.6x - 37.8) / -18

This is the simplified equation for 'K' in terms of 'x'. To solve for specific values of 'K' and 'x', you would need to provide numerical values for the variables 'x' and then calculate 'K' accordingly.
