help me @zairhenrique

OpenStudy (anonymous):

\[-5x-4>21 \iff -21 - 4>5x \iff -25 > 5x \iff -5 > x\]So,\[x<-5\]Did you get it?

OpenStudy (jazzyfa30):

yes

OpenStudy (jazzyfa30):

2x -3 > 23

OpenStudy (anonymous):

\[2x-3>23 \iff 2x>26 \iff x > 13\]

OpenStudy (jazzyfa30):

x - 3 > 2x -1

OpenStudy (anonymous):

\[x-3>2x-1 \iff -2>x \iff x< -2\]

OpenStudy (jazzyfa30):

2(x-5) < 2(2x+3)

OpenStudy (anonymous):

\[2x-10<4x+6 \iff -16<2x \iff -8 < x \iff x>-8\]

OpenStudy (jazzyfa30):

5x -2(x -1) + 11 < 4x -3(x -2) + 5

OpenStudy (anonymous):

\[5x-2x+2+11<4x-3x+6+5 \iff 3x+13 < x + 11 \iff 2x < -2 \iff x<-1\]
