To determine which expression can be substituted for \( x \) in a system of equations, we typically look for an expression that is solved in terms of \( y \).
Normal substitution involves deriving an expression for \( x \) based on an equation. Without the actual system of equations provided, we can't definitively identify which choice is correct from the options you've given. However, it looks like you're looking for a way to express \( x \) in terms of \( y \).
If we assume these expressions are derived from one of the equations in the system, then we would seek to identify the expression that represents \( x \).
The options you've given are:
- A: \( 3y + 14 \)
- B: \( 3y - 14 \)
- C: \( -3y + 14 \)
- D: \( -3y - 14 \)
From the context provided, you should evaluate the expressions based on the original equations that form the system to see if they isolate \( x \).
If we were to substitute expressions to see which one makes \( x \) a function of \( y \), then you should look for an expression that properly isolates \( x \) from the original equations.
Without additional context or the actual equations in the system, I can't ascertain which expression from A, B, C, or D is meant to represent \( x \). Please provide the equations for a more tailored and accurate response.
