Work: Find the solution of equation 9*(1.5+x) = 6.5*(1.765) .
Question type: Equation
Solution:Original question:
| 9 | ( | 3 2 | + | x | ) | = | 13 2 | ( | 353 200 | ) |
| Left side of the equation = | 9 | × | 3 2 | + | 9 | x |
| = | 27 2 | + | 9 | x |
27 2 | + | 9 | x | = | 13 2 | ( | 353 200 | ) |
| Right side of the equation = | 13 2 | × | 353 200 |
| = | 4589 400 |
27 2 | + | 9 | x | = | 4589 400 |
Transposition :
| 9 | x | = | 4589 400 | − | 27 2 |
Combine the items on the right of the equation:
| 9 | x | = | - | 811 400 |
The coefficient of the unknown number is reduced to 1 :
| x | = | - | 811 400 | ÷ | 9 |
| = | - | 811 400 | × | 1 9 |
We obtained :
| x | = | - | 811 3600 |
Convert the result to decimal form :
| x | = | - 0.225278 |
