( | x | − | 180 | ) | × | 3 4 | ÷ | 2400 | = | 0 |
Left side of the equation = | ( | x | − | 180 | ) | × | 1 3200 |
( | x | − | 180 | ) | × | 1 3200 | = | 0 |
Left side of the equation = | x | × | 1 3200 | − | 180 | × | 1 3200 |
= | x | × | 1 3200 | − | 9 160 |
1 3200 | x | − | 9 160 | = | 0 |
1 3200 | x | = | 0 | + | 9 160 |
1 3200 | x | = | 9 160 |
x | = | 9 160 | ÷ | 1 3200 |
= | 9 160 | × | 3200 |
= | 9 | × | 20 |
x | = | 180 |
