Chapter 1: Q25. (page 49)

Solve the equation and check the solution.

x-6=-20

Short Answer

Expert verified

The solution is x=-14.

Step by step solution

01

Step 1- Consider the equation.

Consider the equation x-6=-20.

Add 20 on both sides of the equation.

02

Step 2- Step description.

x鈭�6=鈭�20x鈭�6+20=鈭�20+20x+14=0

03

Step 3- Step description

Subtract 鈭�14from both sides of the equation as follows:

x+14=0x+14鈭�14=鈭�14x=鈭�14

Therefore, the solution is x=-14.

04

Step 4- Verify the solution.

Substitute x=-14in the equation and simplify as follows:

x鈭�6=鈭�20鈭�14鈭�6=鈭�20鈭�20=鈭�20

Since the left-hand side of the equation is equal to the right-hand side of the equation, therefore, the solution is x=-14.
