Understanding the Equation: 3z – 5 = 8z + 2 – A Step-by-Step Algebra Breakdown
Solving linear equations is a foundational skill in algebra, and mastering an equation like 3z – 5 = 8z + 2 opens the door to success in many math challenges. Whether you’re a student learning algebra or someone brushing up on basics, solving for z offers clear, logical steps that build confidence and problem-solving strength. In this article, we’ll walk through solving the equation 3z – 5 = 8z + 2 step-by-step, explain key algebraic principles, and highlight why this type of problem matters.
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

2. Move constant terms to the other side
Now eliminate the constant 2 by subtracting 2 from both sides:
–5 – 2 = 5z To isolate z, divide both sides by 5:
→ –7 = 5z
3. Solve for z
z = –7 ÷ 5
→ z = –1.4
→ z = – rac{7}{5}
