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!
