[ 1/1 Equation]
Work: Find the solution of equation x*0.13+(307145-x)*0.06 = 31367.46 .
Question type: Equation
Solution:Original question:
| x | × | 13 100 | + | ( | 307145 | − | x | ) | × | 3 50 | = | 1568373 50 |
| Left side of the equation = | 13 100 | x | + | 307145 | × | 3 50 | − | x | × | 3 50 |
| = | 13 100 | x | + | 184287 10 | − | x | × | 3 50 |
| = | 7 100 | x | + | 184287 10 |
7 100 | x | + | 184287 10 | = | 1568373 50 |
Transposition :
7 100 | x | = | 1568373 50 | − | 184287 10 |
Combine the items on the right of the equation:
7 100 | x | = | 323469 25 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 323469 25 | ÷ | 7 100 |
| = | 323469 25 | × | 100 7 |
| = | 323469 | × | 4 7 |
We obtained :
| x | = | 1293876 7 |
Convert the result to decimal form :
| x | = | 184839.428571 |
