Work: Find the solution of equation 0.63(w-0.07) = 1 .
Question type: Equation
Solution:Original question:
63 100 | ( | w | − | 7 100 | ) | = | 1 |
| Left side of the equation = | 63 100 | w | − | 63 100 | × | 7 100 |
| = | 63 100 | w | − | 441 10000 |
63 100 | w | − | 441 10000 | = | 1 |
Transposition :
63 100 | w | = | 1 | + | 441 10000 |
Combine the items on the right of the equation:
63 100 | w | = | 10441 10000 |
The coefficient of the unknown number is reduced to 1 :
| w | = | 10441 10000 | ÷ | 63 100 |
| = | 10441 10000 | × | 100 63 |
| = | 10441 100 | × | 1 63 |
We obtained :
| w | = | 10441 6300 |
Convert the result to decimal form :
| w | = | 1.657302 |
