[ 1/1 Equation]
Work: Find the solution of equation -54.21+12.76x+10.54+16.86(x-1.25) = 0 .
Question type: Equation
Solution:Original question:
| - | 5421 100 | + | 319 25 | x | + | 527 50 | + | 843 50 | ( | x | − | 5 4 | ) | = | 0 |
| Left side of the equation = | - | 4367 100 | + | 319 25 | x | + | 843 50 | ( | x | − | 5 4 | ) |
| - | 4367 100 | + | 319 25 | x | + | 843 50 | ( | x | − | 5 4 | ) | = | 0 |
| Left side of the equation = | - | 4367 100 | + | 319 25 | x | + | 843 50 | x | − | 843 50 | × | 5 4 |
| = | - | 4367 100 | + | 319 25 | x | + | 843 50 | x | − | 843 40 |
| = | - | 12949 200 | + | 1481 50 | x |
| - | 12949 200 | + | 1481 50 | x | = | 0 |
Transposition :
1481 50 | x | = | 0 | + | 12949 200 |
Combine the items on the right of the equation:
1481 50 | x | = | 12949 200 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 12949 200 | ÷ | 1481 50 |
| = | 12949 200 | × | 50 1481 |
| = | 12949 4 | × | 1 1481 |
We obtained :
| x | = | 12949 5924 |
Convert the result to decimal form :
| x | = | 2.185854 |
