[ 1/1 Equation]
Work: Find the solution of equation x*0.86*2.91*1.31*1.31 = 3.97 .
Question type: Equation
Solution:Original question:
| x | × | 43 50 | × | 291 100 | × | 131 100 | × | 131 100 | = | 397 100 |
| Left side of the equation = | x | × | 214735593 50000000 |
214735593 50000000 | x | = | 397 100 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 397 100 | ÷ | 214735593 50000000 |
| = | 397 100 | × | 50000000 214735593 |
| = | 397 | × | 500000 214735593 |
We obtained :
| x | = | 198500000 214735593 |
Convert the result to decimal form :
| x | = | 0.924393 |
