see take the variable "x" on one side and constant on other side of inequality sign \[its~like~ x > -4\]

OpenStudy (anonymous):

can you write it out for me?

OpenStudy (anonymous):

@rishavraj

OpenStudy (anonymous):

don't we -3 first?

rishavraj (rishavraj):

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

OpenStudy (anonymous):

I'm confused about why we don't subtract 3 from both sides, first?

TheSmartOne (thesmartone):

\(\sf 2x + 3 > x -1\) \(\sf 2x + 3 -3> x -1 -3\)

rishavraj (rishavraj):

u can even do tht ...u will get same thing ..... \[2x + 3 - 3> x -1 -3\]

TheSmartOne (thesmartone):

They basically skipped a step.

OpenStudy (anonymous):

Oh okay. So now what?

rishavraj (rishavraj):

wht u got????

OpenStudy (anonymous):

\[2x > x -\]

OpenStudy (anonymous):

oops

OpenStudy (anonymous):

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

rishavraj (rishavraj):

which means \[2x > x -4 \] now subtract "x" on both sides....

OpenStudy (anonymous):

\[2 \]

OpenStudy (anonymous):

OMG hold on

OpenStudy (anonymous):

\[ 2 > -4]

OpenStudy (anonymous):

is that right?

rishavraj (rishavraj):

nah its \[x > -4 \] 2x -x = x .......:)
