Work: Find the solution of equation 54×7.98+76.6x = 130.6×7.97 .
Question type: Equation
Solution:Original question:
| 54 | × | 399 50 | + | 383 5 | x | = | 653 5 | × | 797 100 |
| Left side of the equation = | 10773 25 | + | 383 5 | x |
10773 25 | + | 383 5 | x | = | 653 5 | × | 797 100 |
| Right side of the equation = | 520441 500 |
10773 25 | + | 383 5 | x | = | 520441 500 |
Transposition :
383 5 | x | = | 520441 500 | − | 10773 25 |
Combine the items on the right of the equation:
383 5 | x | = | 304981 500 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 304981 500 | ÷ | 383 5 |
| = | 304981 500 | × | 5 383 |
| = | 304981 100 | × | 1 383 |
We obtained :
| x | = | 304981 38300 |
Convert the result to decimal form :
| x | = | 7.96295 |
