Step-by-step solution

To solve the equation 361820x+510x=23+1515x 36 - \frac{18}{20}x + \frac{5}{10}x = 23 + 15 - \frac{1}{5}x , we will follow these steps:

  • Simplify the fractional coefficients for x x .
  • Combine like terms on both sides of the equation.
  • Isolate the terms involving x x on one side and constants on the other side.
  • Solve for x x .

Let's proceed with these steps:

Step 1: Simplify the fractional coefficients.
- 1820\frac{18}{20} simplifies to 910\frac{9}{10}.
- 510\frac{5}{10} simplifies to 12\frac{1}{2}.
- 15\frac{1}{5} is already simplified.

Step 2: Rewrite the original equation using these simplifications:
36910x+12x=23+1515x 36 - \frac{9}{10}x + \frac{1}{2}x = 23 + 15 - \frac{1}{5}x .

Step 3: Combine the constants and terms involving x x .
On the left side, combine 910x -\frac{9}{10}x and +12x +\frac{1}{2}x :
- Convert 12\frac{1}{2} to a denominator of 10: 12=510\frac{1}{2} = \frac{5}{10}.
- Thus, 910x+510x=410x=25x-\frac{9}{10}x + \frac{5}{10}x = -\frac{4}{10}x = -\frac{2}{5}x.

The equation becomes:
3625x=3815x 36 - \frac{2}{5}x = 38 - \frac{1}{5}x .

Step 4: Move all terms involving x x to one side of the equation:
Add 15x\frac{1}{5}x to both sides:
3625x+15x=38 36 - \frac{2}{5}x + \frac{1}{5}x = 38 .
This simplifies to:
3615x=38 36 - \frac{1}{5}x = 38 .

Step 5: Isolate 15x -\frac{1}{5}x :
Subtract 36 from both sides:
15x=2 -\frac{1}{5}x = 2 .

Step 6: Solve for x x by multiplying both sides by 5-5:
x=10 x = -10 .

Therefore, the solution to the equation is x=10 x = -10 .
