5 | ( | 7 2 | - | x | ) | = | 3 | ( | 5 | - | x | ) |
Left side of the equation = | 5 | × | 7 2 | - | 5 | x |
= | 35 2 | - | 5 | x |
35 2 | - | 5 | x | = | 3 | ( | 5 | - | x | ) |
Right side of the equation = | 3 | × | 5 | - | 3 | x |
= | 15 | - | 3 | x |
35 2 | - | 5 | x | = | 15 | - | 3 | x |
- | 5 | x | + | 3 | x | = | 15 | - | 35 2 |
- | 2 | x | = | 15 | - | 35 2 |
- | 2 | x | = | - | 5 2 |
2 | x | = | 5 2 |
x | = | 5 2 | ÷ | 2 |
= | 5 2 | × | 1 2 |
x | = | 5 4 |
x | = | 1.25 |
