3 4 | = | 1 2 | + | ( | x | − | 35 | ) | × | 1 20 | − | ( | 15 | + | 0 | ) | × | 1 20 |
Right side of the equation = | 1 2 | + | x | × | 1 20 | − | 35 | × | 1 20 | − | ( | 15 | + | 0 | ) | × | 1 20 |
= | 1 2 | + | x | × | 1 20 | − | 7 4 | − | ( | 15 | + | 0 | ) | × | 1 20 |
= | - | 5 4 | + | 1 20 | x | − | ( | 15 | + | 0 | ) | × | 1 20 |
= | - | 5 4 | + | 1 20 | x | − | 15 | × | 1 20 | − | 0 | × | 1 20 |
= | - | 5 4 | + | 1 20 | x | − | 3 4 | − | 0 |
= | - | 2 | + | 1 20 | x |
3 4 | = | - | 2 | + | 1 20 | x |
- | 1 20 | x | = | - | 2 | − | 3 4 |
- | 1 20 | x | = | - | 11 4 |
11 4 | = | 1 20 | x |
1 20 | x | = | 11 4 |
x | = | 11 4 | ÷ | 1 20 |
= | 11 4 | × | 20 |
= | 11 | × | 5 |
x | = | 55 |
