An equation is shown.

2 (a+b) = c

Solve the equation for b in terms of a and c. Explain your answer.

A. b=c-2-a; subtract both 2 and a from each side.

B. b=c-2a; distribute 2 to get 2a+b, then subtract 2a from each side.

C. b=c+2a/2; distribute 2 to get 2a+2b, add 2a, then divide by 2.

D. b = c-2a/2; distribute 2 to get 2a+2b, subtract 2a, then divide by 2.

Sincere · Answer 1

2 (a+b) = c

2a + 2b = c

2b = c - 2a

b = (c - 2a) / a

answer

D. b = (c-2a) / 2; distribute 2 to get 2a+2b, subtract 2a, then divide by 2.
