Question

subtract :
$ab \: \: - \: \: 5a \: \: from \: \: 5 b \: \: - ab$
​

Answer 1

Answer:

(ab - 5a) - (5b - ab)

ab - 5a - 5b + ab

ab + ab - 5a - 5b

2ab - 5a - 5b

Answer 2

Question:-

ab-5a From 5b-ab

Answer:-

$\mapsto(ab - 5a )\: from \: (5b - ab)$

Now,

$\: \: \: \: \: \: \: \: \mapsto(5b - ab) - (ab - 5a) \\ \: \mapsto5b - ab - ab + 5a \\ \mapsto - 2ab \: + 5a + 5b$

So, The answer Is

$\mapsto - 2ab \: + 5a + 5b$
