Chapter 1: Q53. (page 25)

Solve each equation. Check your solution.

32z+25-2z-1=78

Short Answer

Expert verified

The required answer is 14.

Step by step solution

01

Step 1- Simplify left side of the equation

Use the distributive property ab+c=ab+acon left side the original equation.

6z+75-2z+2=78

Combine the like terms on left side.

4z+77=78

02

Step 2- Isolate the variable z

Perform subtraction of 77 on both the sides of the equation.

4z+77鈭�77=78鈭�774z=1

Perform division of 4 on both sides of the equation.

4z4=14z=14

03

– Check the obtained value 

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

3214+25鈭�214鈭�1=?783512鈭�2鈭�34=?781532+32=?7878=78

04

Step 4- 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.
