80 | × | 12 | × | 10 | + | 150 | × | 8 | t | = | 80 | × | 30 | × | 10 |
Left side of the equation = | 9600 | + | 1200 | t |
9600 | + | 1200 | t | = | 80 | × | 30 | × | 10 |
Right side of the equation = | 24000 |
9600 | + | 1200 | t | = | 24000 |
1200 | t | = | 24000 | − | 9600 |
1200 | t | = | 14400 |
t | = | 14400 | ÷ | 1200 |
= | 14400 | × | 1 1200 |
= | 12 | × | 1 |
t | = | 12 |
