Error made by parul as solving inequality , she should divide with -5 instead of multiplying and she had to change inequality sine.
What is inequality equation?
Inequality equation is the equation in which the two expressions are compared with greater than, less than or other inequality signs.
Inequality of a graph is represented with the greater then(<), less then(>) or with the other inequity signs. The inequality line on the graph is represented with the dotted lines.
The equation of inequality given as,
[tex]-5x-3.5>6.5-5x-3.5>6.5[/tex]
To solve the above equation, isolate the term x. Add number 3.5 both side of the equation as,
[tex]-5x-3.5+3.5>6.5+3.5-5x-3.5+3.5>6.5+3.5[/tex]
Solve it further as,
[tex]-5x>10-5x>10[/tex]
Divide both the sides of the equation with number -5 as,
[tex]x<10x<10[/tex]
The sign of inequality is changed, as we divide by negative number.
Thus, in final step solving inequality , Parul should divide with -5 instead of multiplying. Parul make one more error as she did not change inequality sine.
