[ 1/1 Equation]
Work: Find the solution of equation x+400*0.2%+x*1.5% = 156 .
Question type: Equation
Solution:Original question:
| x | + | 400 | × | 1 500 | + | x | × | 3 200 | = | 156 |
| Left side of the equation = | x | + | 4 5 | + | x | × | 3 200 |
| = | 203 200 | x | + | 4 5 |
203 200 | x | + | 4 5 | = | 156 |
Transposition :
203 200 | x | = | 156 | − | 4 5 |
Combine the items on the right of the equation:
203 200 | x | = | 776 5 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 776 5 | ÷ | 203 200 |
| = | 776 5 | × | 200 203 |
| = | 776 | × | 40 203 |
We obtained :
| x | = | 31040 203 |
Convert the result to decimal form :
| x | = | 152.906404 |
