Answer 2

Step-by-step explanation:

She should divide both sides by -5 while she multiplied by -5 on other side

and she also did not change the > symbol to a < symbol

Step-by-step explanation:

We are given

-5x-3.5 > 6.5−5x−3.5>6.5

Since, we have to solve for x

so, we will isolate x on anyone side

step-1:

Add both sides by 3.5

-5x-3.5+3.5 > 6.5+3.5−5x−3.5+3.5>6.5+3.5

-5x > 10−5x>10

step-2:

Divide both sides by -5

we know that whenever we divide both sides by negative sign , it's inequality gets revered

so, we get

{-5x}/{-5} < {-50}/{-5}

we get

x < 10x<10

so,

She should divide both sides by -5 while she multiplied by -5 on other side

and she also did not change the > symbol to a < symbol
