[ 1/1 Equation]
Work: Find the solution of equation a*4.3553*（1+10%）+5*0.5645 = 0 .
Question type: Equation
Solution:Original question:
| a | × | 43553 10000 | ( | 1 | + | 10 100 | ) | + | 5 | × | 1129 2000 | = | 0 |
| Left side of the equation = | a | × | 43553 10000 | ( | 1 | + | 10 100 | ) | + | 1129 400 |
| a | × | 43553 10000 | ( | 1 | + | 10 100 | ) | + | 1129 400 | = | 0 |
| Left side of the equation = | a | × | 43553 10000 | × | 1 | + | a | × | 43553 10000 | × | 10 100 | + | 1129 400 |
| = | a | × | 43553 10000 | + | a | × | 43553 100000 | + | 1129 400 |
| = | 479083 100000 | a | + | 1129 400 |
479083 100000 | a | + | 1129 400 | = | 0 |
Transposition :
479083 100000 | a | = | 0 | − | 1129 400 |
Combine the items on the right of the equation:
479083 100000 | a | = | - | 1129 400 |
The coefficient of the unknown number is reduced to 1 :
| a | = | - | 1129 400 | ÷ | 479083 100000 |
| = | - | 1129 400 | × | 100000 479083 |
| = | - | 1129 | × | 250 479083 |
We obtained :
| a | = | - | 282250 479083 |
Convert the result to decimal form :
| a | = | - 0.589146 |
