Answer:
b: -1
Step-by-step explanation:
each number is being multiplied by the value of the letter, so just replace the letters with the numbers they are {like x=-2 would make 3x=3(-2)} in parenthesis, and then subtract
so like 3(-2) - (1) - 3(-2)
(-6) - (1) - (-6)
-6 - 1 + 6 (bc the minus signs cancel each other out)
= -1
God bless!
