Step-by-Step Solution

To solve the equation 27.1913.25x+19.28=13.21x19.2x+11.8 27.19 - 13.25x + 19.28 = 13.21x - 19.2x + 11.8 , we will follow these steps:

  • Simplify each side of the equation.
  • Combine like terms to consolidate x x terms and constant terms separately.
  • Isolate the variable x x on one side of the equation.

Let's start simplification:

1. Simplify the right side of the equation:
13.21x19.2x=(13.2119.2)x=5.99x 13.21x - 19.2x = (13.21 - 19.2)x = -5.99x ,
so the right side becomes 5.99x+11.8 -5.99x + 11.8 .

2. Simplify the left side of the equation:
Combine constants: 27.19+19.28=46.47 27.19 + 19.28 = 46.47 ,
so the left side becomes 46.4713.25x 46.47 - 13.25x .

Our equation now looks like:
46.4713.25x=5.99x+11.8 46.47 - 13.25x = -5.99x + 11.8 .

3. Combine like terms and solve for x x :
Add 5.99x 5.99x to both sides:
46.4713.25x+5.99x=11.8 46.47 - 13.25x + 5.99x = 11.8 ,
Simplifying gives us 46.477.26x=11.8 46.47 - 7.26x = 11.8 .

4. Isolate x x by subtracting 46.47 from both sides:
7.26x=11.846.47 -7.26x = 11.8 - 46.47 .
Simplifying gives 7.26x=34.67 -7.26x = -34.67 .

5. Solve for x x by dividing by 7.26-7.26:
x=34.677.264.77 x = \frac{-34.67}{-7.26} \approx 4.77 .

Therefore, the solution to the equation is x=4.77 x = 4.77 , which matches the correct choice provided.
