Solve each equation. Check your solution.

-34n+1=-11

Short Answer

Expert verified

The required answer is 16.

Step by step solution

01

Step 1- Isolate the variable n

Perform subtraction of 1 from both the sides of the equation.

鈭�34n+1鈭�1=鈭�11鈭�1鈭�34n=鈭�12

Perform division of -34 from both the sides of the equation.

鈭�34n鈭�34=鈭�12鈭�34鈭�43鈭�34n=鈭�12鈰�鈭�43n=16

02

– Check the obtained value 

Substitute the obtained value of n into the original equation and perform simplification for checking.

鈭�3416+1=?鈭�11鈭�12+1=?鈭�11鈭�11=鈭�11

03

Step 3- Make the conclusion

As the checking results in equal values on both the sides on substation of obtained value which means that obtained value is correct.
