Question

Subtract.

Answer 1

Hey Emily070505097, 

Lets solve your problem step by step. 

$(-9.6x+7)-(7.3x-9)$

To solve the problem we have to follow the PEMDAS order of operations. 

$\left(-9.6x+7\right)-\left(7.3x-9\right)$ 

         First, we have to remove the parenthesis. 

⇒ $-9.6x+7-\left(7.3x-9\right)$ 

⇒ $-9.6x+7-7.3x+9$ 

         Now we have to group like terms 

⇒ $-9.6x-7.3x+7+9$

         Next we have to add similar elements  

⇒ $-16.9x+7+9$ 

⇒ $-16.9x+16$

Hope this helps,
