Sagot :
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
Total marbles = 171 = steves + lary’s
X + 3x/7 – 39 = 171
