Answer:
4 is the number.
Step-by-step explanation:
Take the missing number as x,
→ (x × 3) - 4 = (x × 2)
→ 3x - 4 = 2x
→ 3x = 2x + 4
→ 3x - 2x = 4
→ [ x = 4 ]
Hence, the number is 4.
Answer:
x=-8 or x=2
Step-by-step explanation:
x² + 6x - 6 = 10
x² + 6x - 6 - 10 = 0
x² + 6x - 16 = 0
= (x + 8)(x - 2)
x + 8 = 0
x = -8
x - 2 = 0
x = 2
