[ 1/1 Equation]
Work: Find the solution of equation 42*0.85x+12*0.12x = 13000*0.52 .
Question type: Equation
Solution:Original question:
| 42 | × | 17 20 | x | + | 12 | × | 3 25 | x | = | 13000 | × | 13 25 |
| Left side of the equation = | 357 10 | x | + | 36 25 | x |
| = | 1857 50 | x |
1857 50 | x | = | 13000 | × | 13 25 |
| Right side of the equation = | 6760 |
1857 50 | x | = | 6760 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 6760 | ÷ | 1857 50 |
| = | 6760 | × | 50 1857 |
We obtained :
| x | = | 338000 1857 |
Convert the result to decimal form :
| x | = | 182.014001 |
