Answer 2

To simplify :  $12b -32+7b -20 b$

Solution :  

• To simplify $12b -32+7b -20 b$  we combine like terms together and then solve by performing arithmetic operations .
• Like terms are the terms with same variable and power .
• Here terms with same variable $' b'$ are called as like terms and term without variable is called as constant .

• Therefore , we get ,

        $12b -32+7b -20 b$

       $= 12b+7b -20b -32 \\= -b -32$

Hence , on simplifying $12b -32+7b -20 b$ we get $-b -32$ .
