Question

e){2×[20-(5+x)÷6]-5}÷9+17=20​

Answer 1

$e){2×[20-(5+x)÷6]-5}÷9+17=20$

$2 \times (20 - \frac{5 + x}{6} ) - \frac{5}{9} + 17 = 20$

$40 - \frac{5 + x}{3 } - \frac{5}{9} + 17 = 20$

$57 - \frac{5 + x}{3} - \frac{5}{9} = 20$

$\frac{508}{9} - \frac{5 + x}{3} = 20$

$508 - 3 \times (5 + x) = 180$

$508 - 15 - 3x = 180$

$493 - 3x = 180$

$- 3x = 180 - 493$

$- 3x = - 313$

$x = \frac{313}{3}$
