Work: Find the solution of equation 37.16*(x+4) = 0.316x+1.586 .
Question type: Equation
Solution:Original question:
929 25 | ( | x | + | 4 | ) | = | 79 250 | x | + | 793 500 |
| Left side of the equation = | 929 25 | x | + | 929 25 | × | 4 |
| = | 929 25 | x | + | 3716 25 |
929 25 | x | + | 3716 25 | = | 79 250 | x | + | 793 500 |
Transposition :
929 25 | x | − | 79 250 | x | = | 793 500 | − | 3716 25 |
Combine the items on the left of the equation:
9211 250 | x | = | 793 500 | − | 3716 25 |
Combine the items on the right of the equation:
9211 250 | x | = | - | 73527 500 |
The coefficient of the unknown number is reduced to 1 :
| x | = | - | 73527 500 | ÷ | 9211 250 |
| = | - | 73527 500 | × | 250 9211 |
| = | - | 73527 2 | × | 1 9211 |
We obtained :
| x | = | - | 73527 18422 |
Convert the result to decimal form :
| x | = | - 3.99126 |
