3z - 5 = 8z + 2 - ToelettAPP

Understanding the Context

What Does the Equation Mean?

The equation 3z – 5 = 8z + 2 represents a balance between two expressions involving the variable z. The left side (3z – 5) and the right side (8z + 2) are equal, and our goal is to isolate z to find its value. Understanding this balance is crucial — algebra isn’t magic, but logic in action.

Step-By-Step Solution

1. Isolate z terms on one side

Begin by moving all terms with z to one side of the equation. Subtract 3z from both sides:

3z – 5 = 8z + 2  
→ –5 = 5z + 2
```

                                

Now eliminate the constant 2 by subtracting 2 from both sides:


–5 – 2 = 5z
→ –7 = 5z

3. Solve for z

To isolate z, divide both sides by 5:
z = –7 ÷ 5
→ z = –1.4
→ z = –rac{7}{5}

### Final Answer<br/>
The solution to the equation <strong>3z – 5 = 8z + 2</strong> is:<br/>
<strong>z = –rac{7}{5}</strong> (or –1.4 in decimal form).
