Question

Given: x - 8 > -3. Choose the solution set. A. {x | x R, x > -9}B. {x | x R, x > -5}C. {x | x R, x > 5}D. {x | x R, x > 14}

Answer 1

$x-8\ \textgreater \ -3\\ x\ \textgreater \ 5$

C

Answer 2

x - 8 > - 3.Add 8 to both sides: x-8+8>-3+8 or x>+5

The solution of this inequality is {x | x∈R, x>5} (Answer C)
