Question

hamburgers cost $3 and hotdogs cost $2 the total cost of buying b hamburgers and d hotdogs can be expressed by c=3b+2d. how can this equation be solved for d

Answer 1

c = 3b + 2d.....solving for d
subtract 3b from both sides
c - 3b = 2d
divide both sides by 2
(c - 3b) / 2 = d or (c/2) - (3b/2) = d
