Make b be the main item
a=2-(1/1+b)

b=1-a

Step-by-step explanation:

Inside parenthesis

1/1=1

(replace it with that)

Open parenthesis

a=2-1-b

simplify numbers

a=1-b

isolate b

a-1=-b

multiple each side by negative 1

1-a=b

first anwser choice.

step-by-step explanation:

the greater/less or equal to symbol (> or < with the line at the bottom) is a closed/filled in circle.

-5c + 2 _< _27

subtract from both sides by 2

-5c _< _ 27

divide both sides by -5

c _< _ 5.4

flip the inequality sign

c _> _5.4

the only possible answer that would match the simplified inequality is the first answer choice
