[ 1/1 Equation]
Work: Find the solution of equation （5500*12*0.9-0.7*145x*0.064）/（0.3*145x+0.05*145x） = 0.038 .
Question type: Equation
Solution:Original question:
| ( | 5500 | × | 12 | × | 9 10 | − | 7 10 | × | 145 | x | × | 8 125 | ) | ÷ | ( | 3 10 | × | 145 | x | + | 1 20 | × | 145 | x | ) | = | 19 500 |
| Multiply both sides of the equation by: | ( | 3 10 | × | 145 | x | + | 1 20 | × | 145 | x | ) |
| ( | 5500 | × | 12 | × | 9 10 | − | 7 10 | × | 145 | x | × | 8 125 | ) | = | 19 500 | ( | 3 10 | × | 145 | x | + | 1 20 | × | 145 | x | ) |
| 5500 | × | 12 | × | 9 10 | − | 7 10 | × | 145 | x | × | 8 125 | = | 19 500 | ( | 3 10 | × | 145 | x | + | 1 20 | × | 145 | x | ) |
| 5500 | × | 12 | × | 9 10 | − | 7 10 | × | 145 | x | × | 8 125 | = | 19 500 | × | 3 10 | × | 145 | x | + | 19 500 | × | 1 20 | × | 145 | x |
| 59400 | − | 812 125 | x | = | 1653 1000 | x | + | 551 2000 | x |
| 59400 | − | 812 125 | x | = | 3857 2000 | x |
Transposition :
| - | 812 125 | x | − | 3857 2000 | x | = | - | 59400 |
Combine the items on the left of the equation:
| - | 16849 2000 | x | = | - | 59400 |
By shifting the terms and changing the symbols on toth sides of the equation, we obtain :
| 59400 | = | 16849 2000 | x |
If the left side of the equation is equal to the right side, then the right side must also be equal to the left side, that is :
16849 2000 | x | = | 59400 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 59400 | ÷ | 16849 2000 |
| = | 59400 | × | 2000 16849 |
We obtained :
| x | = | 118800000 16849 |
Convert the result to decimal form :
| x | = | 7050.863553 |
