Question

6,8+0,5(x-3)=0,6(х+7)

Answer 1

Ответ:

11

Пошаговое объяснение:

6,8+0,5х-1,5=0,6х+4,2

0,5х-0,6х=4,2-6,8+1,5

-0,1х=-1,1

х=11

Answer 2

6,8+0,5х-1,5=0,6х+4,2
0,1х=-1,1
х=-11

Answer 3

To solve the equation 6.8 + 0.5(x - 3) = 0.6(x + 7), you'll need to simplify and isolate the variable x. Here are the steps to solve it:

1. Distribute the constants on both sides of the equation:

   6.8 + 0.5x - 1.5 = 0.6x + 4.2

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

   6.8 - 1.5 + 0.5x = 0.6x + 4.2

   5.3 + 0.5x = 0.6x + 4.2

3. Move all terms containing x to one side of the equation. You can do this by subtracting 0.6x from both sides:

   5.3 + 0.5x - 0.6x = 4.2

   5.3 - 0.1x = 4.2

4. Next, isolate x by subtracting 5.3 from both sides:

   5.3 - 5.3 - 0.1x = 4.2 - 5.3

   -0.1x = -1.1

5. Finally, solve for x by dividing both sides by -0.1:

   (-0.1x) / (-0.1) = (-1.1) / (-0.1)

   x = 11

So, the solution to the equation is x = 11.
