Determine if substitution or elimination would be more convenient to use for the system below.

• A. Substitution
• B. Elimination

Answer: (A)

Verified step by step guidance

1. First, look at the system of equations: \$3x + y = -3\( and \)2y = -2x$.
2. Rewrite the second equation to isolate \(y\): divide both sides by 2 to get \(y = -x\).
3. Since \(y\) is already isolated in the second equation, substitution is convenient because you can directly substitute \(y = -x\) into the first equation.
4. Substitute \(y = -x\) into the first equation to get \$3x + (-x) = -3$.
5. Now, solve the resulting single-variable equation for \(x\), then use that value to find \(y\).
