Answer 1

Ответ:

2

Пошаговое объяснение:

-3.5z+1=8

-3.5z=8-1

-3.5z=7

z=7:(-3.5)

z=-2

Answer 2

To solve the equation -3.5z + 1 = 8, we'll follow these steps:

Step 1: Move the constant term to the right side by subtracting 1 from both sides of the equation: -3.5z + 1 - 1 = 8 - 1 -3.5z = 7

Step 2: Divide both sides of the equation by -3.5 to isolate z: (-3.5z)/(-3.5) = 7/(-3.5) z = -2

Therefore, the solution to the equation -3.5z + 1 = 8 is z = -2.
