[ 1/1 Equation]
Work: Find the solution of equation x*0.79*2.79*1.05 = 2.8 .
Question type: Equation
Solution:Original question:
| x | × | 79 100 | × | 279 100 | × | 21 20 | = | 14 5 |
| Left side of the equation = | x | × | 462861 200000 |
462861 200000 | x | = | 14 5 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 14 5 | ÷ | 462861 200000 |
| = | 14 5 | × | 200000 462861 |
| = | 2 | × | 40000 66123 |
We obtained :
| x | = | 80000 66123 |
Convert the result to decimal form :
| x | = | 1.209866 |
