Work: Find the solution of equation M98.30%×78.11+（1-98.30%）×92.13 = 0 .
Question type: Equation
Solution:Original question:
| M | × | 983 1000 | × | 7811 100 | + | ( | 1 | − | 983 1000 | ) | × | 9213 100 | = | 0 |
| Left side of the equation = | M | × | 7678213 100000 | + | ( | 1 | − | 983 1000 | ) | × | 9213 100 |
7678213 100000 | M | + | ( | 1 | − | 983 1000 | ) | × | 9213 100 | = | 0 |
| Left side of the equation = | 7678213 100000 | M | + | 1 | × | 9213 100 | − | 983 1000 | × | 9213 100 |
| = | 7678213 100000 | M | + | 9213 100 | − | 9056379 100000 |
| = | 7678213 100000 | M | + | 156621 100000 |
7678213 100000 | M | + | 156621 100000 | = | 0 |
Transposition :
7678213 100000 | M | = | 0 | − | 156621 100000 |
Combine the items on the right of the equation:
7678213 100000 | M | = | - | 156621 100000 |
The coefficient of the unknown number is reduced to 1 :
| M | = | - | 156621 100000 | ÷ | 7678213 100000 |
| = | - | 156621 100000 | × | 100000 7678213 |
| = | - | 156621 | × | 1 7678213 |
We obtained :
| M | = | - | 156621 7678213 |
Convert the result to decimal form :
| M | = | - 0.020398 |
