77 100 | + | 551 100 | x | − | 3 | x | ( | 1 | − | x | ) | = | 1240 | ÷ | 450 |
Left side of the equation = | 77 100 | + | 551 100 | x | − | 3 | x | × | 1 | + | 3 | x | x |
= | 77 100 | + | 551 100 | x | − | 3 | x | + | 3 | x | x |
= | 77 100 | + | 251 100 | x | + | 3 | x | x |
77 100 | + | 251 100 | x | + | 3 | x | x | = | 1240 | ÷ | 450 |
Right side of the equation = | 124 45 |
77 100 | + | 251 100 | x | + | 3 | x | x | = | 124 45 |
