Question

When seventh part of a number is increased by 2,we get the 5th part of the same number decreased by 4.

Answer 1

ATP
$x \div 7 \times + 2 = x \div 5 - 4$
$x \div 7 - x \div 5 = - 4 - 2$
$5x - 7x \div 35 = - 6$
$- 2x = - 6 \times 35$
$2x = 6 \times 35$
$x = 6 \times 35 \div 2 \\ x = 3 \times 35 \\ x = 105$
