Answer 1

$\Huge{\color{skyblue}{\fbox{\textsf{\textbf{Solution :-}}}}}$

Given ,

• (а+b+с)=9
• b(a+b+c) = 16
• с(а+b+c) =144

To find :— a = ?

Now ,

b(a+b+c) = 16

=> b × 9 = 16

=> b = 16/9

And

с(а+b+c) =144

=> c × 9 = 144

=> c = 144/9

=> c = 16

Again ,

а+b+с = 9

=> a + (16/9) + 16 = 9

=> a = 9 - 16 - (16/9)

=> a = 9 - (160/9)

=> a = - 79/9
