Which of the following is an equation with one constant,2 coefficients,and three terms

To identify an equation with one constant, two coefficients, and three terms, we first need to understand the definitions:

- **Constant**: A term that does not change and does not contain any variables (e.g., a number like 4).
- **Coefficients**: Numbers that multiply variables (e.g., in \(3x\), 3 is the coefficient of \(x\)).
- **Terms**: Individual parts of the equation separated by addition or subtraction.

Now, let's analyze each option:

A. \(3x - 4y = 5y\)

- Terms: \(3x\), \(-4y\), \(5y\) (This has three terms but has no constant.)

B. \(3x - y = 5y\)

- Terms: \(3x\), \(-y\), \(5y\) (This also has three terms but has no constant.)

C. \(3x - 4 = 5y\)

- Terms: \(3x\), \(-4\), \(5y\) (This has three terms, one constant \(-4\), and two coefficients: \(3\) (for \(x\)) and \(5\) (for \(y\)).)

D. \(3x - 4y = 5x\)

- Terms: \(3x\), \(-4y\), \(5x\) (This has three terms but has no constant.)

Based on the analysis, the correct option that fits the description of having one constant, two coefficients, and three terms is:

**C. \(3x - 4 = 5y\)**
