| ( | 19 500 | + | 37 1000 | + | 37 1000 | + | x | ) | ÷ | 4 | = | 37 1000 |
| Left side of the equation = | 19 500 | × | 1 4 | + | 37 1000 | × | 1 4 | + | 37 1000 | × | 1 4 | + | x | × | 1 4 |
| = | 19 2000 | + | 37 4000 | + | 37 4000 | + | x | × | 1 4 |
| = | 7 250 | + | 1 4 | x |
7 250 | + | 1 4 | x | = | 37 1000 |
1 4 | x | = | 37 1000 | − | 7 250 |
1 4 | x | = | 9 1000 |
| x | = | 9 1000 | ÷ | 1 4 |
| = | 9 1000 | × | 4 |
| = | 9 250 | × | 1 |
| x | = | 9 250 |
| x | = | 0.036 |
