Empat (4) orang menggali parit dan selesai dalam waktu 7 hari. Berapa orang yang diperlukan untuk menggali parit dalam waktu 1/2 hari?

( -5 + x ) * y = - 90;

y = 1 => x = -85; or, y = -1 => x = 95;
y = 2 => x = -40; or, y = -2 => x = 50;
y = 3 => x = -25; or, y = -3 => x = 40;
y = 5 => x = -13; or, y = -5=> x = 23;
y = 6 => x = - 11; or, y = -6 => x = 20;
y = 9 => x = -5; or, y = -9=> x = 15;
y = 10 => x = -4; or, y = -10 => x = 14;
y = 15 => x = -3; or, y = -15=> x = 13;
y = 16 => x = 0; or y = -16 => x = 10;
y = 30 => x = 2; or, y = -30=> x = 8;
y = 90 => x = 4; or, y = -90 => x = 6;

The two numbers that add up to -5 and multiply to -90 are 10 and -9, or -10 and 5. Both pairs satisfy the conditions given in the problem. Using the sum and product equations allows us to find these numbers step-by-step.
