[ 1/1 Equation]
Work: Find the solution of equation x = 2*(0.945*0.719)/(0.945+0.719) .
Question type: Equation
Solution:Original question:
| x | = | 2 | ( | 189 200 | × | 719 1000 | ) | ÷ | ( | 189 200 | + | 719 1000 | ) |
| Multiply both sides of the equation by: | ( | 189 200 | + | 719 1000 | ) |
| x | ( | 189 200 | + | 719 1000 | ) | = | 2 | ( | 189 200 | × | 719 1000 | ) |
| x | × | 189 200 | + | x | × | 719 1000 | = | 2 | ( | 189 200 | × | 719 1000 | ) |
| x | × | 189 200 | + | x | × | 719 1000 | = | 2 | × | 189 200 | × | 719 1000 |
| x | × | 189 200 | + | x | × | 719 1000 | = | 135891 100000 |
208 125 | x | = | 135891 100000 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 135891 100000 | ÷ | 208 125 |
| = | 135891 100000 | × | 125 208 |
| = | 135891 800 | × | 1 208 |
We obtained :
| x | = | 135891 166400 |
Convert the result to decimal form :
| x | = | 0.816653 |
