Work: Find the solution of equation x*99.975%-120.138*100.025% = 1/10 .
Question type: Equation
Solution:Original question:
| x | × | 3999 4000 | − | 60069 500 | × | 4001 4000 | = | 1 | ÷ | 10 |
| Left side of the equation = | x | × | 3999 4000 | − | 240336069 2000000 |
3999 4000 | x | − | 240336069 2000000 | = | 1 | ÷ | 10 |
| Right side of the equation = | 1 10 |
3999 4000 | x | − | 240336069 2000000 | = | 1 10 |
Transposition :
3999 4000 | x | = | 1 10 | + | 240336069 2000000 |
Combine the items on the right of the equation:
3999 4000 | x | = | 240536069 2000000 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 240536069 2000000 | ÷ | 3999 4000 |
| = | 240536069 2000000 | × | 4000 3999 |
| = | 240536069 500 | × | 1 3999 |
We obtained :
| x | = | 240536069 1999500 |
Convert the result to decimal form :
| x | = | 120.298109 |
