14−3n=−10

Short Answer

Expert verified

The required answer is 8.

Step by step solution

01

Step 1- Isolate the variable n

Perform subtraction of 14 on both sides of the equation.

14−3n−14=−10−14−3n=−24

Perform division of on both sides of the equation.

−3n−3=−24−3n=8

02

– Check the obtained value 

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

14−3(8)=?−1014−24=?−10−10=−10

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.
