Question

Solve for y: 3y - 5 = 10

• A. 3
• B. 5
• C. 6
• D. 7

Hint:

Always perform inverse operations to solve for a variable. The inverse of subtraction is addition, and the inverse of multiplication is division. Apply them in the reverse order of operations (reverse PEMDAS).

Answer 1

The Correct Option is B

Step 1: Understanding the Concept:
This is a two-step linear equation. We need to perform two operations to isolate the variable \(y\).
Step 2: Detailed Explanation:
The given equation is:
\[ 3y - 5 = 10 \] First, add 5 to both sides:
\[ 3y = 10 + 5 \] \[ 3y = 15 \] Next, divide both sides by 3:
\[ y = \frac{15}{3} \] \[ y = 5 \] Step 3: Final Answer:
The value of \(y\) is 5. This corresponds to option (B).
