Question

Evaluate each expression for 8a-(4+b)

Answer 1

Hey there! 

First we have to distribute the negative terms 

Like: 

$8a + (-1) (4 + a)\\ \\ = 8a+ (-1) *4(-1a) \\ \\ = 8a + (-4) + (-a)$

Combine like terms

Like: 

$8a, -a\\ \\ -4 \\ \\ 8a + (-4) + (-a)\\ \\ = 8a + (-a) + (-4) \\ \\ = 7a + (-4)$

$Answer: 7a - 4$

Good luck on your assignment and enjoy your day!
