Question

Evaluate the expression below when g = -6.

-3g - 2 -(-4g + 10)

Answer 1

replace all copies of g with -6 and evaluate

-3g - 2 -(-4g + 10)

-3(-6) - 2 -(-4(-6) + 10)

18 - 2 - (24 + 10)

I'll let you finish

Answer 2

....I got 3

Answer 3

I'll keep going

Answer 4

18 - 2 - (24 + 10)

18 - 2 - (34)

18 - 2 - 34

16 - 34

-18

So -3(-6) - 2 -(-4(-6) + 10) = -18

This means -3g - 2 -(-4g + 10) = -18 when g = -6

Answer 5
