Question

Variable b is 7 more than variable c. Variable b is also 1 less than variable c. Which pair of equations best models the relationship between b and c?

b = c + 7
b = c – 1 b = c – 7
b = c + 1 c = b + 7
c = b – 1 c = b – 7
c = b – 1

Answer 1

I believe the correct answer is:
b = c - 1; b = c - 7
