( | 92 | + | 96 | + | 97 | + | 300 | + | x | ) | ÷ | 7 | = | 189 2 |
Left side of the equation = | 92 | × | 1 7 | + | 96 | × | 1 7 | + | 97 | × | 1 7 | + | 300 | × | 1 7 | + | x | × | 1 7 |
= | 92 7 | + | 96 7 | + | 97 7 | + | 300 7 | + | x | × | 1 7 |
= | 585 7 | + | 1 7 | x |
585 7 | + | 1 7 | x | = | 189 2 |
1 7 | x | = | 189 2 | − | 585 7 |
1 7 | x | = | 153 14 |
x | = | 153 14 | ÷ | 1 7 |
= | 153 14 | × | 7 |
= | 153 2 | × | 1 |
x | = | 153 2 |
x | = | 76.5 |
