Work: Find the solution of equation 0.474*（20+19.878x) = 2*19.187*0.688 .
Question type: Equation
Solution:Original question:
237 500 | ( | 20 | + | 9939 500 | x | ) | = | 2 | × | 19187 1000 | × | 86 125 |
| Left side of the equation = | 237 500 | × | 20 | + | 237 500 | × | 9939 500 | x |
| = | 237 25 | + | 2355543 250000 | x |
237 25 | + | 2355543 250000 | x | = | 2 | × | 19187 1000 | × | 86 125 |
| Right side of the equation = | 825041 31250 |
237 25 | + | 2355543 250000 | x | = | 825041 31250 |
Transposition :
2355543 250000 | x | = | 825041 31250 | − | 237 25 |
Combine the items on the right of the equation:
2355543 250000 | x | = | 528791 31250 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 528791 31250 | ÷ | 2355543 250000 |
| = | 528791 31250 | × | 250000 2355543 |
| = | 528791 | × | 8 2355543 |
We obtained :
| x | = | 4230328 2355543 |
Convert the result to decimal form :
| x | = | 1.795904 |
