2 | ( | 5 | + | x | ) | = | 50 | + | 200 | − | 2 | x |
Left side of the equation = | 2 | × | 5 | + | 2 | x |
= | 10 | + | 2 | x |
10 | + | 2 | x | = | 50 | + | 200 | − | 2 | x |
Right side of the equation = | 250 | − | 2 | x |
10 | + | 2 | x | = | 250 | − | 2 | x |
2 | x | + | 2 | x | = | 250 | − | 10 |
4 | x | = | 250 | − | 10 |
4 | x | = | 240 |
x | = | 240 | ÷ | 4 |
= | 240 | × | 1 4 |
= | 60 | × | 1 |
x | = | 60 |
