[ 1/1 Equation]
Work: Find the solution of equation 172.1447+0.02212x = 167.9367+(x-11.2)/4 .
Question type: Equation
Solution:Original question:
1721447 10000 | + | 553 25000 | x | = | 1679367 10000 | + | ( | x | − | 56 5 | ) | ÷ | 4 |
| Right side of the equation = | 1679367 10000 | + | x | × | 1 4 | − | 56 5 | × | 1 4 |
| = | 1679367 10000 | + | x | × | 1 4 | − | 14 5 |
| = | 1651367 10000 | + | 1 4 | x |
1721447 10000 | + | 553 25000 | x | = | 1651367 10000 | + | 1 4 | x |
Transposition :
553 25000 | x | − | 1 4 | x | = | 1651367 10000 | − | 1721447 10000 |
Combine the items on the left of the equation:
| - | 5697 25000 | x | = | 1651367 10000 | − | 1721447 10000 |
Combine the items on the right of the equation:
| - | 5697 25000 | x | = | - | 876 125 |
By shifting the terms and changing the symbols on toth sides of the equation, we obtain :
876 125 | = | 5697 25000 | 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 :
5697 25000 | x | = | 876 125 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 876 125 | ÷ | 5697 25000 |
| = | 876 125 | × | 25000 5697 |
| = | 292 | × | 200 1899 |
We obtained :
| x | = | 58400 1899 |
Convert the result to decimal form :
| x | = | 30.753028 |
