Solution

Find the addition of $5 a - 7 b, 3 b - 4 a + 2, 2 a - 3 a b - 5$
Add all the algebraic expressions by putting plus sign,
$5 a - 7 b + 3 b - 4 a + 2 + 2 a - 3 a b - 5 = 5 a - 4 a + 2 a - 7 b + 3 b - 3 a b + 2 - 5 = a + 2 a - 4 b - 3 a b + 2 - 5 = 3 a - 4 b - 3 a b - 3 ∴ 5 a - 7 b + 3 b - 4 a + 2 + 2 a - 3 a b - 5 = 3 a - 4 b - 3 a b - 3$
