Solve the equation. Check your solution.

12-4s=-12

Short Answer

Expert verified

The solution for the equation 12-4s=-12 is s=6.

Step by step solution

01

Step 1. Separate the variable and constants

Write the original equation and separate the variables.

12鈭�4s=鈭�12鈭�4s=鈭�12鈭�12鈭�4s=鈭�24

02

Step 2. Solve for f

Now, divide both sides of the equation by -4.

s=鈭�24鈭�4s=6

Therefore, the solution of the equation is s=6.

03

Step 3. Check the solution 

To check the solution, write the original equation and substitute the value of s.

12-4s=-12

Now, substitutes=6 and check the result.

12鈭�46=鈭�1212鈭�24=鈭�12鈭�12=鈭�12

As the left-hand side is equal to right hand side, this signifies that the solution is correct.
