[ 1/1 Equation]
Work: Find the solution of equation 0.85*42x+0.15*20X = 33315*0.53 .
Question type: Equation
Solution:Original question:
17 20 | × | 42 | x | + | 3 20 | × | 20 | x | = | 33315 | × | 53 100 |
| Left side of the equation = | 357 10 | x | + | 3 | x |
| = | 387 10 | x |
387 10 | x | = | 33315 | × | 53 100 |
| Right side of the equation = | 353139 20 |
387 10 | x | = | 353139 20 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 353139 20 | ÷ | 387 10 |
| = | 353139 20 | × | 10 387 |
| = | 117713 2 | × | 1 129 |
We obtained :
| x | = | 117713 258 |
Convert the result to decimal form :
| x | = | 456.251938 |
