Work: Find the solution of equation （64+124x）*0.0439936 = 4*0.21*x .
Question type: Equation
Solution:Original question:
| ( | 64 | + | 124 | x | ) | × | 3437 78125 | = | 4 | × | 21 100 | x |
| Left side of the equation = | 64 | × | 3437 78125 | + | 124 | x | × | 3437 78125 |
| = | 219968 78125 | + | 426188 78125 | x |
219968 78125 | + | 426188 78125 | x | = | 4 | × | 21 100 | x |
| Right side of the equation = | 21 25 | x |
219968 78125 | + | 426188 78125 | x | = | 21 25 | x |
Transposition :
426188 78125 | x | − | 21 25 | x | = | - | 219968 78125 |
Combine the items on the left of the equation:
360563 78125 | x | = | - | 219968 78125 |
The coefficient of the unknown number is reduced to 1 :
| x | = | - | 219968 78125 | ÷ | 360563 78125 |
| = | - | 219968 78125 | × | 78125 360563 |
| = | - | 31424 | × | 1 51509 |
We obtained :
| x | = | - | 31424 51509 |
Convert the result to decimal form :
| x | = | - 0.610068 |
