Work: Find the solution of equation （4-0.75）*0.2796*x = 0.019 .
Question type: Equation
Solution:Original question:
| ( | 4 | − | 3 4 | ) | × | 699 2500 | x | = | 19 1000 |
| Left side of the equation = | 4 | × | 699 2500 | x | − | 3 4 | × | 699 2500 | x |
| = | 699 625 | x | − | 2097 10000 | x |
| = | 9087 10000 | x |
9087 10000 | x | = | 19 1000 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 19 1000 | ÷ | 9087 10000 |
| = | 19 1000 | × | 10000 9087 |
| = | 19 | × | 10 9087 |
We obtained :
| x | = | 190 9087 |
Convert the result to decimal form :
| x | = | 0.020909 |
