Work: Find the solution of equation (1665+1040x-770.56)*1.8*1.08*1.2 = 1873 .
Question type: Equation
Solution:Original question:
| ( | 1665 | + | 1040 | x | − | 19264 25 | ) | × | 9 5 | × | 27 25 | × | 6 5 | = | 1873 |
| Left side of the equation = | ( | 1665 | + | 1040 | x | − | 19264 25 | ) | × | 1458 625 |
| ( | 1665 | + | 1040 | x | − | 19264 25 | ) | × | 1458 625 | = | 1873 |
| Left side of the equation = | 1665 | × | 1458 625 | + | 1040 | x | × | 1458 625 | − | 19264 25 | × | 1458 625 |
| = | 485514 125 | + | 303264 125 | x | − | 28086912 15625 |
| = | 32602338 15625 | + | 303264 125 | x |
32602338 15625 | + | 303264 125 | x | = | 1873 |
Transposition :
303264 125 | x | = | 1873 | − | 32602338 15625 |
Combine the items on the right of the equation:
303264 125 | x | = | - | 3336713 15625 |
The coefficient of the unknown number is reduced to 1 :
| x | = | - | 3336713 15625 | ÷ | 303264 125 |
| = | - | 3336713 15625 | × | 125 303264 |
| = | - | 3336713 125 | × | 1 303264 |
We obtained :
| x | = | - | 3336713 37908000 |
Convert the result to decimal form :
| x | = | - 0.088021 |
