[ 1/1 Equation]
Work: Find the solution of equation 1.21*0.79*1.31*x*1.09 = 3.19 .
Question type: Equation
Solution:Original question:
121 100 | × | 79 100 | × | 131 100 | x | × | 109 100 | = | 319 100 |
| Left side of the equation = | 136492961 100000000 | x |
136492961 100000000 | x | = | 319 100 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 319 100 | ÷ | 136492961 100000000 |
| = | 319 100 | × | 100000000 136492961 |
| = | 29 | × | 1000000 12408451 |
We obtained :
| x | = | 29000000 12408451 |
Convert the result to decimal form :
| x | = | 2.337117 |
