A + B + C = 408
B = C + 7 = A + 5 ... A = B - 5 ... C = B - 7
solve by substitution
Abel ,Belle and Cindy have $408 altogether. Belle has $7 more than Cindy And $5 more than Abel. how much does Abel have?
4 answers
Cindy has $X.
Belle has $(X+7).
Abel has $(X+7)-5.
x + (x+7) + (x+7)-5 = 408.
3x = 399,
X = 133.
Abel amt. = (x+7)-5 = (133 + 7)- 5 = $135.
