1 40 | + | 13 10 | ( | x | − | 1 40 | ) | = | 11 50 |
Left side of the equation = | 1 40 | + | 13 10 | x | − | 13 10 | × | 1 40 |
= | 1 40 | + | 13 10 | x | − | 13 400 |
= | - | 3 400 | + | 13 10 | x |
- | 3 400 | + | 13 10 | x | = | 11 50 |
13 10 | x | = | 11 50 | + | 3 400 |
13 10 | x | = | 91 400 |
x | = | 91 400 | ÷ | 13 10 |
= | 91 400 | × | 10 13 |
= | 7 40 | × | 1 |
x | = | 7 40 |
x | = | 0.175 |
