[ 1/1 Equation]
Work: Find the solution of equation x*99.98%-91.202*100.02% = -30/90 .
Question type: Equation
Solution:Original question:
| x | × | 4999 5000 | − | 45601 500 | × | 5001 5000 | = | - | 30 | ÷ | 90 |
| Left side of the equation = | x | × | 4999 5000 | − | 228050601 2500000 |
4999 5000 | x | − | 228050601 2500000 | = | - | 30 | ÷ | 90 |
| Right side of the equation = | - | 1 3 |
4999 5000 | x | − | 228050601 2500000 | = | - | 1 3 |
Transposition :
4999 5000 | x | = | - | 1 3 | + | 228050601 2500000 |
Combine the items on the right of the equation:
4999 5000 | x | = | 681651803 7500000 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 681651803 7500000 | ÷ | 4999 5000 |
| = | 681651803 7500000 | × | 5000 4999 |
| = | 681651803 1500 | × | 1 4999 |
We obtained :
| x | = | 681651803 7498500 |
Convert the result to decimal form :
| x | = | 90.905088 |
