263 | + | x | = | 87 100 | ( | 345 | + | x | ) |
Right side of the equation = | 87 100 | × | 345 | + | 87 100 | x |
= | 6003 20 | + | 87 100 | x |
263 | + | x | = | 6003 20 | + | 87 100 | x |
x | − | 87 100 | x | = | 6003 20 | − | 263 |
13 100 | x | = | 6003 20 | − | 263 |
13 100 | x | = | 743 20 |
x | = | 743 20 | ÷ | 13 100 |
= | 743 20 | × | 100 13 |
= | 743 | × | 5 13 |
x | = | 3715 13 |
x | = | 285.769231 |
