Question

0,21х-15/56=3/16+257/800х

Answer 1

0,21х - 0,27 = 0,1875 + 0,32х
0,21х - 0,32х = 0,1875 +  0,27
- 0,11х = 0,4575
х = - 4,16

Answer 2

To solve the equation for x, follow these steps:

1. First, let's get rid of the fractions by multiplying both sides of the equation by the least common multiple (LCM) of the denominators. In this case, the LCM is 56.

   (56 * 0.21x) - (56 * 15/56) = (56 * 3/16) + (56 * 257/800x)

   11.76x - 15 = 105 + 179.15x

2. Now, let's move all terms containing x to one side of the equation and constants to the other side. You can do this by subtracting 179.15x from both sides and adding 15 to both sides:

   11.76x - 179.15x = 105 + 15

   -167.39x = 120

3. Finally, solve for x by dividing both sides by -167.39:

   x = 120 / -167.39

   x ≈ -0.716

So, the solution to the equation is approximately x ≈ -0.716.
