[ 1/1 Equation]
Work: Find the solution of equation 12.18x = （x+3.5）×8.98 .
Question type: Equation
Solution:Original question:
609 50 | x | = | ( | x | + | 7 2 | ) | × | 449 50 |
| Right side of the equation = | x | × | 449 50 | + | 7 2 | × | 449 50 |
| = | x | × | 449 50 | + | 3143 100 |
609 50 | x | = | 449 50 | x | + | 3143 100 |
Transposition :
609 50 | x | − | 449 50 | x | = | 3143 100 |
Combine the items on the left of the equation:
16 5 | x | = | 3143 100 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 3143 100 | ÷ | 16 5 |
| = | 3143 100 | × | 5 16 |
| = | 3143 20 | × | 1 16 |
We obtained :
| x | = | 3143 320 |
Convert the result to decimal form :
| x | = | 9.821875 |
