[ 1/2 Equation]
Work: Find the solution of equation X+(X-100)*(194*0.005) = 352.3 .
Question type: Equation
Solution:Original question:
| X | + | ( | X | − | 100 | ) | ( | 194 | × | 1 200 | ) | = | 3523 10 |
| Left side of the equation = | X | + | X | ( | 194 | × | 1 200 | ) | − | 100 | ( | 194 | × | 1 200 | ) |
| = | X | + | X | × | 194 | × | 1 200 | − | 100 | ( | 194 | × | 1 200 | ) |
| = | X | + | X | × | 97 100 | − | 100 | ( | 194 | × | 1 200 | ) |
| = | 197 100 | X | − | 100 | ( | 194 | × | 1 200 | ) |
| = | 197 100 | X | − | 100 | × | 194 | × | 1 200 |
| = | 197 100 | X | − | 97 |
197 100 | X | − | 97 | = | 3523 10 |
Transposition :
197 100 | X | = | 3523 10 | + | 97 |
Combine the items on the right of the equation:
197 100 | X | = | 4493 10 |
The coefficient of the unknown number is reduced to 1 :
| X | = | 4493 10 | ÷ | 197 100 |
| = | 4493 10 | × | 100 197 |
| = | 4493 | × | 10 197 |
We obtained :
| X | = | 44930 197 |
Convert the result to decimal form :
| X | = | 228.071066 |
[ 2/2 Equation]
Work: Find the solution of equation x-(x-100)/1+32 = 422 .
Question type: Equation
Solution:Original question:
| x | − | ( | x | − | 100 | ) | ÷ | 1 | + | 32 | = | 422 |
| Left side of the equation = | x | − | x | × | 1 | + | 100 | × | 1 | + | 32 |
| = | x | − | x | × | 1 | + | 100 | + | 32 |
| = | 0 | x | + | 132 |
| 0 | x | + | 132 | = | 422 |
Transposition :
| = | 422 | − | 132 |
