"Those guarantees of the Bill of Rights which are fundamental safeguards of liberty... are equally protected against state invasion...
Reason and reflection require us to recognize that in our adversary
system of criminal justice, any person haled into court, who is too
poor to hire a lawyer, cannot be assured a fair trial unless counsel is
provided for him."
Justice Hugo Black, 1963

they thoght they were going to nuke each other

i also think it is c

its c not d   tell me if that´s correct

simplify brackets

8 - 2a - 7 = a + 40

simplify 8 - 2a - 7 to -2a + 1

-2a + 1 = a + 40

add 2a to both sides

1 = a + 40 + 2a

simplify a + 40 + 2a to 3a + 40

1 = 3a + 40

subtract 40 from both sides

1 - 40 = 3a

simplify 1 - 40 o -39

-39 = 3a

divide both sides by 3

-39/3 = a

simplify 39/3 to 13

-13 = a

switch sides

a = -13
