[ 1/1 Equation]
Work: Find the solution of equation 70×1.5x十80×1.5x = 3655.17 .
Question type: Equation
Solution:Original question:
| 70 | × | 3 2 | x | + | 80 | × | 3 2 | x | = | 365517 100 |
| Left side of the equation = | 105 | x | + | 120 | x |
| = | 225 | x |
| 225 | x | = | 365517 100 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 365517 100 | ÷ | 225 |
| = | 365517 100 | × | 1 225 |
| = | 40613 100 | × | 1 25 |
We obtained :
| x | = | 40613 2500 |
Convert the result to decimal form :
| x | = | 16.2452 |
