Larry and Steve have 171 marbles in all. The number of marbles Larry has is 39 fewer than 3/7 of the number of marbles Steve has. How many marbles does Steve have?

Steve = x marbles, Larry = 3x/7 - 39 marbles

Total marbles = 171 = steves + lary’s

X + 3x/7 - 39 = 171

X + 3x/7 = 171 + 39

10x/7 = 210

10x = 210 * 7

10x = 1470 X = 147

Larry = 3/7 (147) - 39

Larry = 63 - 39 = 24

Steve = 147

Total marbles = 147 + 24 = 171
