Work: Find the solution of equation ((63-60)*0.03+x)*2.15+1.55 = 7.1355 .
Question type: Equation
Solution:Original question:
| ( | ( | 63 | − | 60 | ) | × | 3 100 | + | x | ) | × | 43 20 | + | 31 20 | = | 14271 2000 |
| Left side of the equation = | ( | 63 | − | 60 | ) | × | 3 100 | × | 43 20 | + | x | × | 43 20 | + | 31 20 |
| = | ( | 63 | − | 60 | ) | × | 129 2000 | + | x | × | 43 20 | + | 31 20 |
| = | 63 | × | 129 2000 | − | 60 | × | 129 2000 | + | 43 20 | x | + | 31 20 |
| = | 8127 2000 | − | 387 100 | + | 43 20 | x | + | 31 20 |
| = | 3487 2000 | + | 43 20 | x |
3487 2000 | + | 43 20 | x | = | 14271 2000 |
Transposition :
43 20 | x | = | 14271 2000 | − | 3487 2000 |
Combine the items on the right of the equation:
43 20 | x | = | 674 125 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 674 125 | ÷ | 43 20 |
| = | 674 125 | × | 20 43 |
| = | 674 25 | × | 4 43 |
We obtained :
| x | = | 2696 1075 |
Convert the result to decimal form :
| x | = | 2.507907 |
