Question

Given: A= {18, 6, -3, -12}
Determine all the elements of set A that are in the solution of the inequality 2/3 (two-thirds) x + 3 < -2x-7.

Answer 1

is the 2/3 for x or for x +3

Answer 2

itd be best just to solve for the inequality and see what matches :)

Answer 3

add 2x and subtract 3 from both side; then divide out you constant on the x

Answer 4

2/3x+2x +3-3 < -2x+2x -7-3

8/3 x < -10 ; * 3/8

x < -80/3

Answer 5

err.... x < -30/8 :)

-15/4 = -3' 3/4

Answer 6

that answer appears to be -12; but dbl chk
