Question

Solve for B.
A = 3(B + C)
B = (A - C)/3
B = (3A - C)/3
B = (A - 3C)/3

Answer 1

something's wrong with the q

Answer 2

B=(A-3C)/3
Multiply the denominator up and it works.

Answer 3

i think u've provided the options only and not the expression from which we r supposed to find the answer

Answer 4

B=(A/3) - C

B=(A/3) - (3C/3)

B=(A-3C)/3

Answer 5

B = (3(B+C) - C) / 3
B = (3B + 2C) / 3

(3(B+C) - C) = (3(3(B+C)) - C) = (3(B+C) - 3C)

2B = (3(3(B+C)) - C) + (3(B+C) - 3C)
2B = 12B + 8C
8C = 10B
C = 10B/8

-10B = 8C
B = 8C/10
B = (4 / 5) / -19
B = 4/-95

Answer 6

The question might be missing a few parts, and in that case the answer would be wrong. But if that's the question, then my answer should be correct.

Answer 7

I agree, I just noticed it isn't clear what the original equation was or if one has been presented with 4 equations to solve for B.
