10 | = | ( | 3 5 | − | 4 25 | X | ) | ( | 9 | − | X | ) |
Right side of the equation = | 3 5 | ( | 9 | − | X | ) | − | 4 25 | X | ( | 9 | − | X | ) |
= | 3 5 | × | 9 | − | 3 5 | X | − | 4 25 | X | ( | 9 | − | X | ) |
= | 27 5 | − | 3 5 | X | − | 4 25 | X | ( | 9 | − | X | ) |
= | 27 5 | − | 3 5 | X | − | 4 25 | X | × | 9 | + | 4 25 | X | X |
= | 27 5 | − | 3 5 | X | − | 36 25 | X | + | 4 25 | X | X |
= | 27 5 | − | 51 25 | X | + | 4 25 | X | X |
10 | = | 27 5 | − | 51 25 | X | + | 4 25 | X | X |
