Work: Find the solution of equation 5.4x+2.7(x+9.3) = 2.7x+51.57 .
Question type: Equation
Solution:Original question:
27 5 | x | + | 27 10 | ( | x | + | 93 10 | ) | = | 27 10 | x | + | 5157 100 |
| Left side of the equation = | 27 5 | x | + | 27 10 | x | + | 27 10 | × | 93 10 |
| = | 27 5 | x | + | 27 10 | x | + | 2511 100 |
| = | 81 10 | x | + | 2511 100 |
81 10 | x | + | 2511 100 | = | 27 10 | x | + | 5157 100 |
Transposition :
81 10 | x | − | 27 10 | x | = | 5157 100 | − | 2511 100 |
Combine the items on the left of the equation:
27 5 | x | = | 5157 100 | − | 2511 100 |
Combine the items on the right of the equation:
27 5 | x | = | 1323 50 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 1323 50 | ÷ | 27 5 |
| = | 1323 50 | × | 5 27 |
| = | 49 10 | × | 1 |
We obtained :
| x | = | 49 10 |
Convert the result to decimal form :
| x | = | 4.9 |
