Work: Find the solution of equation ((800-12168.93)+x)*0.75/30000 = 0.05 .
Question type: Equation
Solution:Original question:
| ( | ( | 800 | − | 1216893 100 | ) | + | x | ) | × | 3 4 | ÷ | 30000 | = | 1 20 |
| Left side of the equation = | ( | ( | 800 | − | 1216893 100 | ) | + | x | ) | × | 1 40000 |
| ( | ( | 800 | − | 1216893 100 | ) | + | x | ) | × | 1 40000 | = | 1 20 |
| Left side of the equation = | ( | 800 | − | 1216893 100 | ) | × | 1 40000 | + | x | × | 1 40000 |
| = | 800 | × | 1 40000 | − | 1216893 100 | × | 1 40000 | + | 1 40000 | x |
| = | 1 50 | − | 1216893 4000000 | + | 1 40000 | x |
| = | - | 1136893 4000000 | + | 1 40000 | x |
| - | 1136893 4000000 | + | 1 40000 | x | = | 1 20 |
Transposition :
1 40000 | x | = | 1 20 | + | 1136893 4000000 |
Combine the items on the right of the equation:
1 40000 | x | = | 1336893 4000000 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 1336893 4000000 | ÷ | 1 40000 |
| = | 1336893 4000000 | × | 40000 |
| = | 1336893 100 | × | 1 |
We obtained :
| x | = | 1336893 100 |
Convert the result to decimal form :
| x | = | 13368.93 |
