dikali berapa hasilnya 6 dikurang berapa hasilnya 1

a × b = 6
a - b = 1

a - b = 1
a = 1 + b

a × b = 6
(1 + b) × b = 6
b² + b - 6 = 0
(b - 2)(b + 3) = 0
b = 2 (memenuhi)
b = -3 (tidak memenuhi)

maka b = 2

a = 1 + b
a = 1 + 2
a = 3

a × b = 6 → 3 × 2 = 6
a - b = 1 → 3 - 2 = 1

Semoga berguna +_+
