How solving 2x>-14 is different from solving -2x>14 ? Explain.

Short Answer

Expert verified

The solution for the inequality is x>-7.

Step by step solution

01

Step -1 - Apply the concept of Linear inequalities

In this type of inequality, Simply use the property of addition or subtraction or multiplication of suitable number on both Left Hand Side & Right Hand Sideto maintain the inequality and also the variable & numbers should be at the different sides in the equation.

02

Step -2 – Find the value of xof first inequality

Since, the equality is2x>-14.

Here, to simplify this inequality, divide2to both side on the above

2x>鈭�142x2>鈭�142x>鈭�7

03

Step -3 – Find the value of x of second inequality

Since, the equality is -2x>14.

Here, to simplify this inequality, divide -2to both side on the above

鈭�2x>14鈭�2x鈭�2>14鈭�2x>鈭�7

Here, in first to get the solution, it has to divide with 2 and in second case, it has to divide by -2.
