Solve the equation.

51 - 2z - 8z = 23

Z=2.8

Step-by-step explanation:

51-10z=28

(/10) = 2.8

Answer: z=2.8

This is how I do!

Step-by-step explanation:

51-2z-8z=23

We simplify the equation to the form, which is simple to understand

51-2z-8z=23

We move all terms containing z to the left and all other terms to the right.

-2z-8z=+23-51

We simplify left and right side of the equation.

-10z=-28

We divide both sides of the equation by - 10 to get z.

z=2.8
