200 | ( | x | − | 3 | ) | = | 150 | ( | x | + | 5 | ) |
Left side of the equation = | 200 | x | − | 200 | × | 3 |
= | 200 | x | − | 600 |
200 | x | − | 600 | = | 150 | ( | x | + | 5 | ) |
Right side of the equation = | 150 | x | + | 150 | × | 5 |
= | 150 | x | + | 750 |
200 | x | − | 600 | = | 150 | x | + | 750 |
200 | x | − | 150 | x | = | 750 | + | 600 |
50 | x | = | 750 | + | 600 |
50 | x | = | 1350 |
x | = | 1350 | ÷ | 50 |
= | 1350 | × | 1 50 |
= | 27 | × | 1 |
x | = | 27 |
