Question

Solve 6k + 9 > k – 1.

Answer 1

Answer:

k > - 2

Step-by-step explanation:

subtract k from both sides

5k + 9 > - 1 ( subtract 9 from both sides )

5k > - 10 ( divide both sides by 5 )

k > - 2

Answer 2

$Solution, 6k+9>k-1\quad :\quad \begin{bmatrix}\mathrm{Solution:}\:&\:x>-2\:\\ \:\mathrm{Interval\:Notation:}&\:\left(-2,\:\infty \:\right)\end{bmatrix}$

$6k+9>k-1$

$\mathrm{Subtract\:}9\mathrm{\:from\:both\:sides},\\6k+9-9>k-1-9$

$\mathrm{Simplify},\\6k>k-10$

$\mathrm{Subtract\:}k\mathrm{\:from\:both\:sides},\\6k-k>k-10-k$

$\mathrm{Simplify},\\5k>-10$

$\mathrm{Divide\:both\:sides\:by\:}5,\\\frac{5k}{5}>\frac{-10}{5}$

$\mathrm{Simplify},\\k>-2$

$The\:Correct\:Answer\:Is\:k>-2$
