Work: Find the solution of equation 0.15*15x+0.85*38x = 27000*0.53 .
Question type: Equation
Solution:Original question:
3 20 | × | 15 | x | + | 17 20 | × | 38 | x | = | 27000 | × | 53 100 |
| Left side of the equation = | 9 4 | x | + | 323 10 | x |
| = | 691 20 | x |
691 20 | x | = | 27000 | × | 53 100 |
| Right side of the equation = | 14310 |
691 20 | x | = | 14310 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 14310 | ÷ | 691 20 |
| = | 14310 | × | 20 691 |
We obtained :
| x | = | 286200 691 |
Convert the result to decimal form :
| x | = | 414.182344 |
