Work: Find the solution of equation 2.02X-4.0804 = 0.81*0.45X .
Question type: Equation
Solution:Original question:
101 50 | X | − | 10201 2500 | = | 81 100 | × | 9 20 | X |
| Right side of the equation = | 729 2000 | X |
101 50 | X | − | 10201 2500 | = | 729 2000 | X |
Transposition :
101 50 | X | − | 729 2000 | X | = | 10201 2500 |
Combine the items on the left of the equation:
3311 2000 | X | = | 10201 2500 |
The coefficient of the unknown number is reduced to 1 :
| X | = | 10201 2500 | ÷ | 3311 2000 |
| = | 10201 2500 | × | 2000 3311 |
| = | 10201 5 | × | 4 3311 |
We obtained :
| X | = | 40804 16555 |
Convert the result to decimal form :
| X | = | 2.464754 |
