X | = | ( | 7 | + | 77 50 | + | X | ) | × | 9 100 |
Right side of the equation = | 7 | × | 9 100 | + | 77 50 | × | 9 100 | + | X | × | 9 100 |
= | 63 100 | + | 693 5000 | + | X | × | 9 100 |
= | 3843 5000 | + | 9 100 | X |
X | = | 3843 5000 | + | 9 100 | X |
X | − | 9 100 | X | = | 3843 5000 |
91 100 | X | = | 3843 5000 |
X | = | 3843 5000 | ÷ | 91 100 |
= | 3843 5000 | × | 100 91 |
= | 549 50 | × | 1 13 |
X | = | 549 650 |
X | = | 0.844615 |
