350 | ( | x | + | 5 | ) | = | 300 | ( | x | + | 10 | ) |
Left side of the equation = | 350 | x | + | 350 | × | 5 |
= | 350 | x | + | 1750 |
350 | x | + | 1750 | = | 300 | ( | x | + | 10 | ) |
Right side of the equation = | 300 | x | + | 300 | × | 10 |
= | 300 | x | + | 3000 |
350 | x | + | 1750 | = | 300 | x | + | 3000 |
350 | x | − | 300 | x | = | 3000 | − | 1750 |
50 | x | = | 3000 | − | 1750 |
50 | x | = | 1250 |
x | = | 1250 | ÷ | 50 |
= | 1250 | × | 1 50 |
= | 25 | × | 1 |
x | = | 25 |
