( | 40221 1000 | + | x | ) | × | 31 20 | = | 40221 1000 | + | 35121 500 | − | x |
Left side of the equation = | 40221 1000 | × | 31 20 | + | x | × | 31 20 |
= | 1246851 20000 | + | x | × | 31 20 |
1246851 20000 | + | 31 20 | x | = | 40221 1000 | + | 35121 500 | − | x |
Right side of the equation = | 110463 1000 | − | x |
1246851 20000 | + | 31 20 | x | = | 110463 1000 | − | x |
31 20 | x | + | x | = | 110463 1000 | − | 1246851 20000 |
51 20 | x | = | 110463 1000 | − | 1246851 20000 |
51 20 | x | = | 962409 20000 |
x | = | 962409 20000 | ÷ | 51 20 |
= | 962409 20000 | × | 20 51 |
= | 320803 1000 | × | 1 17 |
x | = | 320803 17000 |
