Work: Find the solution of equation 15%x-120 = 10%+120 .
Question type: Equation
Solution:Original question:
15 100 | x | − | 120 | = | 10 100 | + | 120 |
| Right side of the equation = | 1201 10 |
15 100 | x | − | 120 | = | 1201 10 |
Transposition :
15 100 | x | = | 1201 10 | + | 120 |
Combine the items on the right of the equation:
15 100 | x | = | 2401 10 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 2401 10 | ÷ | 15 100 |
| = | 2401 10 | × | 100 15 |
| = | 2401 | × | 10 15 |
We obtained :
| x | = | 24010 15 |
By reducing fraction, we can get:
| x | = | 4802 3 |
Convert the result to decimal form :
| x | = | 1600.666667 |
