318 5 | t | ( | 40 | − | 2 | t | ) | = | 200 | ( | t | + | 2142 | t | ) |
| Left side of the equation = | 318 5 | t | × | 40 | − | 318 5 | t | × | 2 | t |
| = | 2544 | t | − | 636 5 | t | t |
| 2544 | t | − | 636 5 | t | t | = | 200 | ( | t | + | 2142 | t | ) |
| Right side of the equation = | 200 | t | + | 200 | × | 2142 | t |
| = | 200 | t | + | 428400 | t |
| = | 428600 | t |
| 2544 | t | − | 636 5 | t | t | = | 428600 | t |
