[ 1/1 Equation]
Work: Find the solution of equation 168.9541-0.102379x = 164.2728+(x-11.2)/4 .
Question type: Equation
Solution:Original question:
1689541 10000 | − | 102379 1000000 | x | = | 205341 1250 | + | ( | x | − | 56 5 | ) | ÷ | 4 |
| Right side of the equation = | 205341 1250 | + | x | × | 1 4 | − | 56 5 | × | 1 4 |
| = | 205341 1250 | + | x | × | 1 4 | − | 14 5 |
| = | 201841 1250 | + | 1 4 | x |
1689541 10000 | − | 102379 1000000 | x | = | 201841 1250 | + | 1 4 | x |
Transposition :
| - | 102379 1000000 | x | − | 1 4 | x | = | 201841 1250 | − | 1689541 10000 |
Combine the items on the left of the equation:
| - | 352379 1000000 | x | = | 201841 1250 | − | 1689541 10000 |
Combine the items on the right of the equation:
| - | 352379 1000000 | x | = | - | 74813 10000 |
By shifting the terms and changing the symbols on toth sides of the equation, we obtain :
74813 10000 | = | 352379 1000000 | 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 :
352379 1000000 | x | = | 74813 10000 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 74813 10000 | ÷ | 352379 1000000 |
| = | 74813 10000 | × | 1000000 352379 |
| = | 74813 | × | 100 352379 |
We obtained :
| x | = | 7481300 352379 |
Convert the result to decimal form :
| x | = | 21.230834 |
