[ 1/1 Equation]
Work: Find the solution of equation 0.4x+2 = 0.046（1.06x+8） .
Question type: Equation
Solution:Original question:
2 5 | x | + | 2 | = | 23 500 | ( | 53 50 | x | + | 8 | ) |
| Right side of the equation = | 23 500 | × | 53 50 | x | + | 23 500 | × | 8 |
| = | 1219 25000 | x | + | 46 125 |
2 5 | x | + | 2 | = | 1219 25000 | x | + | 46 125 |
Transposition :
2 5 | x | − | 1219 25000 | x | = | 46 125 | − | 2 |
Combine the items on the left of the equation:
8781 25000 | x | = | 46 125 | − | 2 |
Combine the items on the right of the equation:
8781 25000 | x | = | - | 204 125 |
The coefficient of the unknown number is reduced to 1 :
| x | = | - | 204 125 | ÷ | 8781 25000 |
| = | - | 204 125 | × | 25000 8781 |
| = | - | 68 | × | 200 2927 |
We obtained :
| x | = | - | 13600 2927 |
Convert the result to decimal form :
| x | = | - 4.646396 |
