x | × | 61 20 | + | 3 | × | 23 10 | = | ( | x | + | 3 | ) | × | 76 25 |
Left side of the equation = | x | × | 61 20 | + | 69 10 |
61 20 | x | + | 69 10 | = | ( | x | + | 3 | ) | × | 76 25 |
Right side of the equation = | x | × | 76 25 | + | 3 | × | 76 25 |
= | x | × | 76 25 | + | 228 25 |
61 20 | x | + | 69 10 | = | 76 25 | x | + | 228 25 |
61 20 | x | − | 76 25 | x | = | 228 25 | − | 69 10 |
1 100 | x | = | 228 25 | − | 69 10 |
1 100 | x | = | 111 50 |
x | = | 111 50 | ÷ | 1 100 |
= | 111 50 | × | 100 |
= | 111 | × | 2 |
x | = | 222 |
