Work: Find the solution of equation 12.7%+x+12.7%x = -1.7% .
Question type: Equation
Solution:Original question:
127 1000 | + | x | + | 127 1000 | x | = | - | 17 1000 |
| Left side of the equation = | 127 1000 | + | 1127 1000 | x |
127 1000 | + | 1127 1000 | x | = | - | 17 1000 |
Transposition :
1127 1000 | x | = | - | 17 1000 | − | 127 1000 |
Combine the items on the right of the equation:
1127 1000 | x | = | - | 18 125 |
The coefficient of the unknown number is reduced to 1 :
| x | = | - | 18 125 | ÷ | 1127 1000 |
| = | - | 18 125 | × | 1000 1127 |
| = | - | 18 | × | 8 1127 |
We obtained :
| x | = | - | 144 1127 |
Convert the result to decimal form :
| x | = | - 0.127773 |
