Question

I’m trying to do this equation I put the right question but it dosent work pls help ASAP

Answer 1

x < 10

set builder notation: (-∞ , 10)

Explanation:

2(x - 4) < 12

multiply left side out:

2x - 8 < 12

add 8 to both sides:

2x - 8 + 8 < 12 + 8

2x < 20

divide both sides by 2:

2x/2 < 20/2

x < 10

in set builder notation: (-∞ , 10)
