Solve each equation. Check your solution.

4.3n+1=7-1.7n

Short Answer

Expert verified

The required answer is 1.

Step by step solution

01

Step 1- Isolate the variable n

Perform addition of 1.7n and subtraction of 1 on both the sides of the equation.

4.3n+1+1.7n鈭�1=7鈭�1.7n+1.7n鈭�16n=6

Perform division of 6 on both the sides of the equation

6n6=66n=1

02

– Check the obtained value 

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

4.31+1=?7鈭�1.714.3+1=?7鈭�1.75.3=5.3

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.
