Consistent or Inconsistent? Solve each system of equations by substitution or elimination. Determine whether the system is consistent and independent, consistent and dependent, or inconsistent. 2. \begin{cases} 2x + 3y = -5 \ -6x - 6y = 15 \end{cases} 3. \begin{cases} y = \frac{1}{2}x \ 2x + y = 2 \end{cases}

Step 1
From the second equation, we have y = ix. Substituting this into the first equation, we get Zx + 3(ix) = -5. Simplifying, we have Zx + 3ix = -5. Combining like terms, we have (Z + 3i)x = -5. Since x is a variable and Z and i are constants, we can rewrite this Show more…
