290 | + | x | = | 87 100 | ( | 335 | + | x | ) |
Right side of the equation = | 87 100 | × | 335 | + | 87 100 | x |
= | 5829 20 | + | 87 100 | x |
290 | + | x | = | 5829 20 | + | 87 100 | x |
x | − | 87 100 | x | = | 5829 20 | − | 290 |
13 100 | x | = | 5829 20 | − | 290 |
13 100 | x | = | 29 20 |
x | = | 29 20 | ÷ | 13 100 |
= | 29 20 | × | 100 13 |
= | 29 | × | 5 13 |
x | = | 145 13 |
x | = | 11.153846 |
