Solve the equation. Check your solution.

h3-14=-11

Short Answer

Expert verified

The solution for the equation is h=9.

Step by step solution

01

Step 1.  Apply the concept of Linear Equation

In this type of equation, simply use the tools of mathematical operations like addition, subtraction, multiplication or division to eliminate the numbers in the equation and also maintaining the equality by using the proper numbers and get the result.

02

Step 2.  Find the value of h by solving the inequality

Since, the equation is h3-14=-11.

Here, to simplify this equation, adding 14to both side on the above

h3鈭�14=鈭�11h3鈭�14+14=鈭�11+14h3=3h=3脳3h=9

03

Step 3.  Check the equation to verify the equality

Since, the solution is, h=9and the equation is h3-14=-11.

So,

Put h=9in equation,

Left鈥夆赌�Hand鈥�Side:=h3鈭�14=93鈭�14=3鈭�14=鈭�11=Right鈥�Hand鈥�Side

It holds the equation.

So, the solution h=9 correctly holds the equation.
