Answer:

Z=8 is the answer

Explanation:

first, you add 8 to both sides which leaves you with 5z=40. then after that you divide both sides by 5 which leaves you with 5/5z = 40/5. then buy dividing 5 by 5 its leaves you with 1 which is equal to z because blank variables equal 1. On the other side if the equation 40 by 5 is 8 so that leaves you with z=8

Explanation:


\tt{5z - 8 = 32}

We want to remove the 8 first.

Step 1 : Since the original equation is minus 8 , we are going to use the opposite operation and add 8 to both sides.


\tt{5z - 8 + 8 = 32 + 8}

Simplify -8 + 8 = 0 on the left. 32 + 8 = 40 on the right. Then we need to think about how to remove the coefficient 5.


\tt{5z = 40}

Step 2 : Since the opposite of multiplication is division , we are going to divide both sides by 5.


\tt{ (5z)/(5) = (40)/(5)}

Simplify. 5 / 5 = 1 on the left. 40/5 = 8 on the right. So , our answer is z = 8.


\tt{z = 8}


\pink{ \boxed{ \boxed{ \text{Our \: final \: answer : \boxed{ \underline{ \tt{z = 8}}}}}}}

Hope I helped ! ♡

Have a wonderful day / night ! ツ
