Alice Valenzuela · Answer 1

Z=6. first, you want to get the z/2 by itself, so you subtract the 7 from both sides. you then get 3=z/2, and then multiply by two because multiplication is the opposite of division, so you can get the z alone. you then get z=6 because 3x2=6

Rey · Answer 2

Answer: z = 6

Step-by-step explanation: Isolating the unknown variable, we write:

z/2 = 10 - 7; z/2 = 3; z = 3.2 = 6.
