Question 1051746
Which system of equations cannot be
directly solved by applying the elimination
method?
A. 12𝑥 − 11𝑦 = −4
   −6𝑥 − 11𝑦 = 7
B. 𝑥 − 11𝑦 = −6
   𝑥 + 12𝑦 = −7
C. 7𝑥 + 11𝑦 = 12
  −6𝑥 − 4𝑦 = −21
D. 𝑥 + 11𝑦 = 7
   11𝑦 − 12𝑥 = 4
<pre>It's NOT B and D. It's C, because A, B, and D CAN be solved, DIRECTLY, using the elimination method.
