Question

Given the replacement set is { – 8 , – 6 , – 4 , 3 , 6 , 8 , 12 }
Solve:

( x – 1 ) + 4 < 10

Answer 1

Step-by-step explanation:

Given the replacement set is { – 8 , – 6 , – 4 , 3 , 6 , 8 , 12 }

Solve:

( x – 1 ) + 4 < 10

Answer 2

Answer:

2/3 (x – 1) + 4 < 10

⇒ 2/3 (x – 1) < 10 – 4

⇒ 2/3 (x - 1) < 6

⇒ 2(x – 1) < 18

⇒ x – 1 < 9

⇒ x – 1 + 1 < 9 + 1(Adding 1 to both sides)

⇒ x < 10

Thus x < 10

Since replacement set = {-8, -6, -4, 3, 6, 8, 12}

⇒ Solution set = {-8, -6, -4, 3, 6, 8}
