1223 | + | 8 | ( | 8 | x | − | 140 | ) | = | 10 | ( | 5 | x | − | 33 | ) | + | 615 |
Left side of the equation = | 1223 | + | 8 | × | 8 | x | − | 8 | × | 140 |
= | 1223 | + | 64 | x | − | 1120 |
= | 103 | + | 64 | x |
103 | + | 64 | x | = | 10 | ( | 5 | x | − | 33 | ) | + | 615 |
Right side of the equation = | 10 | × | 5 | x | − | 10 | × | 33 | + | 615 |
= | 50 | x | − | 330 | + | 615 |
= | 50 | x | + | 285 |
103 | + | 64 | x | = | 50 | x | + | 285 |
64 | x | − | 50 | x | = | 285 | − | 103 |
14 | x | = | 285 | − | 103 |
14 | x | = | 182 |
x | = | 182 | ÷ | 14 |
= | 182 | × | 1 14 |
= | 13 | × | 1 |
x | = | 13 |
