Question

3/4(7x-1)-(x/7-x-2)= 72

Answer 1

Solution:-

given by :-

3/4(7x-1)-(x/7-x-2)= 72

$\frac{3}{4} (7x - 1) - ( \frac{x}{7} - x - 2) = 72 \\ \frac{21x - 3}{4} - ( \frac{x - 7x - 14}{7} ) = 72 \\ \frac{147x - 21 - 4x + 28x + 56}{28} = 72 \\ 171x + 35 = 2016 \\ 171x = 1981 \\ x = \frac{1981}{171}$
