2 | x | + | 52 | + | 10 | = | ( | 2 | x | + | 2 | × | 10 | ) | × | 2 |
Left side of the equation = | 2 | x | + | 62 |
2 | x | + | 62 | = | ( | 2 | x | + | 2 | × | 10 | ) | × | 2 |
Right side of the equation = | 2 | x | × | 2 | + | 2 | × | 10 | × | 2 |
= | 4 | x | + | 40 |
2 | x | + | 62 | = | 4 | x | + | 40 |
2 | x | − | 4 | x | = | 40 | − | 62 |
- | 2 | x | = | 40 | − | 62 |
- | 2 | x | = | - | 22 |
22 | = | 2 | x |
2 | x | = | 22 |
x | = | 22 | ÷ | 2 |
= | 22 | × | 1 2 |
= | 11 | × | 1 |
x | = | 11 |
