Parul attempted to solve an inequality but made one or more errors. her work and the graph she drew are shown below. what errors did parul make? check all that apply. she added 3.5 to both sides when she should have subtracted. she should have divided both sides by as her first step. she divided one side by -5 while multiplying the other side by -5. she did not change the > symbol to a < symbol. she used a closed circle instead of an open circle on the number line.

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

Since, we have to solve for x

so, we will isolate x on anyone side

step-1:

Add both sides by 3.5

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

we get

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

answer: i think it is (1,-2)

the answer will be
