In this SEO-optimized guide, we’ll break down 3(0) – 2y = 6 step-by-step, explain how to solve for y, and highlight why understanding such equations is essential for math learners.
What Is the Equation 3(0) – 2y = 6?
The equation 3(0) – 2y = 6 is a linear equation in one variable (y). Although multiplying zero by 3 may seem confusing at first, recognizing that 3(0) = 0 simplifies the expression significantly. This lets us focus on the essential components: isolating y by simple algebraic manipulation.
Why Is This Equation Useful to Learn?
Working with equations like 3(0) – 2y = 6 helps students build foundational skills in:
- Simplifying expressions
- Applying the order of operations
- Isolating variables
- Understanding algebraic structure
Moreover, equations involving no variable (like 3(0)) guide learners to distinguish between constant substitutions and true variable equations — an important distinction in solving algebra problems effectively.
Step-by-Step Solution: How to Solve 3(0) – 2y = 6
Let’s solve 3(0) – 2y = 6 step by step:
Step 1: Simplify Constants
Since 3(0) = 0, replace 3(0) with 0:
0 – 2y = 6
Step 2: Rewrite to Standard Form
Move constants to one side:
–2y = 6
It’s standard to express equations with positive coefficients, so multiply both sides by –1:
2y = –6
Step 3: Solve for y
Divide both sides by 2:
y = –6 ÷ 2
y = –3
Final Answer
The solution to the equation 3(0) – 2y = 6 is:
y = –3
