[ 1/1 Equation]
Work: Find the solution of equation (1.9-1.795834)*100 = 120*X/60 .
Question type: Equation
Solution:Original question:
| ( | 19 10 | − | 897917 500000 | ) | × | 100 | = | 120 | X | ÷ | 60 |
| Left side of the equation = | 19 10 | × | 100 | − | 897917 500000 | × | 100 |
| = | 190 | − | 897917 5000 |
| = | 52083 5000 |
52083 5000 | = | 120 | X | ÷ | 60 |
| Right side of the equation = | 2 | X |
52083 5000 | = | 2 | X |
Transposition :
| - | 2 | X | = | - | 52083 5000 |
By shifting the terms and changing the symbols on toth sides of the equation, we obtain :
52083 5000 | = | 2 | X |
If the left side of the equation is equal to the right side, then the right side must also be equal to the left side, that is :
| 2 | X | = | 52083 5000 |
The coefficient of the unknown number is reduced to 1 :
| X | = | 52083 5000 | ÷ | 2 |
| = | 52083 5000 | × | 1 2 |
We obtained :
| X | = | 52083 10000 |
Convert the result to decimal form :
| X | = | 5.2083 |
