Answer:
z = 6
Step by step explanation:
We have 3z, 2z, and 1z
Therefore, you will add all the z’s together to get 6z.
Next, you will add all the single numbers (10,12,2, and 1) to get 25.
We will put this all together as an equation
6z + 25 = 61
Subtract 61 and 25 to get 36
6z = 36
Divide 36 and 6 to get 6
z = 6
