Work: Find the solution of equation 383.2+4x = (106+x)*3.72 .
Question type: Equation
Solution:Original question:
1916 5 | + | 4 | x | = | ( | 106 | + | x | ) | × | 93 25 |
| Right side of the equation = | 106 | × | 93 25 | + | x | × | 93 25 |
| = | 9858 25 | + | x | × | 93 25 |
1916 5 | + | 4 | x | = | 9858 25 | + | 93 25 | x |
Transposition :
| 4 | x | − | 93 25 | x | = | 9858 25 | − | 1916 5 |
Combine the items on the left of the equation:
7 25 | x | = | 9858 25 | − | 1916 5 |
Combine the items on the right of the equation:
7 25 | x | = | 278 25 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 278 25 | ÷ | 7 25 |
| = | 278 25 | × | 25 7 |
| = | 278 | × | 1 7 |
We obtained :
| x | = | 278 7 |
Convert the result to decimal form :
| x | = | 39.714286 |
